Non-Negotiable Accuracy Rule

Do not write guide instructions from memory when the property, connector field, or formula behavior is risky. Search the local Microsoft docs mirror and the curated reference pack first. If the answer is not present, verify with current Microsoft Learn or live Power Apps behavior, then add the result to the curated reference pack.

Reference Pack Reading Order

For building a new app from scratch: 1. builder-system.md — requirements gathering, naming conventions, YAML generation rules, Patch templates, publishing workflow 2. real-build-quirks.md — live editor confirmed quirks 3. live-build-lessons.md — lessons from Training Tracker GitHub issues (bugs diagnosed and fixed in production) 4. ui-patterns.md — reusable YAML patterns (panels, tab nav, error borders, pill galleries, status colours) 5. verified-control-reference.md — exact property lists per control 6. external/powerappsui/README.md — pre-built component library (data table, KPI cards, charts, sidebar, stepper, dialog, etc.) — check before hand-building a UI pattern this already covers 7. powerfx-patterns.md — formula reference 8. known-bad-patterns.md — patterns that must never appear 9. sharepoint-office365users.md — SharePoint list and connector patterns

Real Build Quirks To Preserve

• SharePoint list names with spaces must be wrapped in single quotes, for example 'TT Personnel'.
• Layer order matters: background/card/panel/gallery-row controls must sit behind the controls they support.
• Temporary red-line formula errors must be called out when a later control, collection, or variable resolves them.
• Property tables should distinguish required changes from default/safety-check values.
• Use powerapps-control-defaults.md before adding visual/default property lists to guide rows.
• Sort order must use full enum names, for example SortOrder.Ascending, not bare Ascending.
• Modern Combo box hint text uses InputTextPlaceholder, not Placeholder.
• Modern Combo box display text must be explicit with ItemDisplayText.
• In the Training Tracker day-filtering formulas, preserve the exact working day-unit spelling from the live editor. If the app accepted "Days" and rejected bare Days, do not normalize it away.
• Modern Toggle state is handled with Checked in this guide family.
• Office365Users connector casing differs by operation. Preserve the exact field casing used by the verified operation.

Known Bad Patterns

Known Bad Patterns

Last checked: 2026-07-08

These are mistakes that must not reappear in this guide family.

Read this before generalizing any entry below into "avoid this whole control." Every entry here documents ONE specific broken property or pattern on a control, not a blanket verdict on the control itself. A control having one confirmed bug is not evidence that a different symptom on that same control shares the same root cause. Before recommending a full control swap because "this control is already known to be broken," re-check that the specific property causing the current symptom is the same one named in the entry — if it isn't, diagnose the new symptom fresh, don't reach for the existing fix. (This rule exists because a full ModernDatePicker swap got recommended for a one-character Format string bug, off the back of an entry below about a completely unrelated SelectedDate bug on the same control — see feedback_minimal_fix_before_destructive in memory.)

Blacklisted Controls — Do Not Use, In Any Project

• Copilot answer (preview) modern control. User directive 2026-07-05: do not propose, verify, or insert this control anywhere, in any Power Apps project across this whole family — not a "low priority, verify later" item, an outright blacklist. Reason given: likely government/organisational cost or licensing tier attached to AI/Copilot features at work. Do not suggest it as an option even when a feature genuinely sounds like a good fit for it.
• Header modern control (ModernHeader). Verified 2026-07-05 against Microsoft's own docs: "Unsupported capabilities: Customization of colors, App navigation." It only exposes Title/Logo/IsProfilePictureVisible — no way to add custom action buttons (Save/Close/Delete etc.) or nav links. Cannot replace a hand-built action-bar top bar. Don't propose it for that purpose again.
• Card modern control (ModernCard@1.0.0). Verified 2026-07-05: fixed, non-composable template (Title/Subtitle/Description/Image + a single OnSelect for the whole card). Does not support layering independent action buttons (edit/delete icons, "Open in App") on top of a full-card click target — the pattern every link/dashboard card in this app family actually needs. Don't propose it as a replacement for hand-built card patterns.
• ModernTabList (TabListCanvas) / Tabs modern control. User directive 2026-07-06: blacklisted, do not use in any project. Confirmed broken even by Microsoft's own standard — pasting Microsoft's own published example markup for this control straight from their docs into the browser editor throws errors, it's not a Policy Tracker-specific formula mistake. Don't propose it as a segmented-tab/filter replacement for hand-built tab rows.

Control Properties

• GroupContainer@1.5.0 (both ManualLayout and AutoLayout variants) has DropShadow ON by default when the property is left unset. Not a visible/obvious default — you have to explicitly write DropShadow: =DropShadow.None on every single container to turn it off, or every card/row/panel in a whole screen gets an unwanted shadow. Confirmed the hard way on Policy Tracker ViewItem_1: every container across the whole screen had a stray drop shadow because this was never set, and it had to be manually stripped from each one after the fact. Always set DropShadow: =DropShadow.None explicitly on every GroupContainer unless a shadow is actually wanted for that specific one (e.g. a modal card popping over a dimmed background) — never rely on the unset/default state being "no shadow."

• Modern Combo box with Placeholder. Use InputTextPlaceholder.

• Modern Combo box with record-shaped Items and no explicit ItemDisplayText. Use the field that exists in Items, for example ThisItem.DisplayName for Office365Users search rows.
• ModernCombobox dropdown panel renders as an empty/"ghost" outline with no list content — after ruling out every formula-level cause. Confirmed on Policy Tracker ViewItem_1's cmb_Owner1: the three invalid properties documented above (FontWeight: ="", Appearance.FilledLighter, AllowExternalSelectedItems) were fixed, DefaultSelectedItems correctly pre-selected a real value, and the Items formula (Office365Users.SearchUserV2({...isSearchTermRequired: false...}).value) already matched every commonly-documented working pattern — yet the dropdown list still opened empty and typing did nothing. This is a Microsoft-acknowledged platform limitation, not a fixable formula bug: on an official Power Platform community thread about a Modern dropdown-family control going blank, a Microsoft employee's own reply states verbatim: "Modern controls are not that stable, it displays blank dropdown menu from time to time." Do not keep iterating on ModernCombobox formulas/properties once the above are ruled out — revert to the Classic ComboBox@0.0.51 control instead. That control is not visually "classic-ugly" by default — it supports BorderRadius (rounded corners) and Appearance: ='ComboboxCanvas.Appearance'.FilledLighter, so it can be styled to match a modern design without the ModernCombobox instability. It needs ComboBoxDataField@1.5.0 children (set via the Data/"Edit fields" panel, not hand-typed) to define which fields — e.g. DisplayName, Mail — are searchable/displayed, which ModernCombobox doesn't require (ItemDisplayText replaces that need on the Modern version). 2026-07-05.
• ModernCombobox (ComboboxCanvas) completely unresponsive — can't type in the search box, dropdown arrow does nothing, looks present but dead. Checked against Microsoft's current official docs property-by-property (not a guess) and found three invalid values causing it: FontWeight: ="" (only FontWeight.Bold/Semibold/Normal/Lighter are valid — bare "" isn't a real enum value and can stop the control initializing at all), Appearance: =Appearance.FilledLighter (not a real enum member — only Appearance.Filled, Appearance.FilledDarker, Appearance.Outline exist), and AllowExternalSelectedItems (not a documented property of this control at all). Fix: delete FontWeight and AllowExternalSelectedItems entirely (or set FontWeight to a real enum value), and change Appearance to Appearance.Filled or .FilledDarker. Also confirmed while investigating: this control's old TriggerOutput property was renamed to DelayOutput in a recent Microsoft update (TriggerOutput = "FocusOut" → DelayOutput = true) — if a paste still has TriggerOutput, that's stale, not the unresponsiveness cause itself. Policy Tracker ViewItem_1's cmb_Owner1, 2026-07-05.
• Modern Text input with HintText. Use Placeholder.
• Modern Toggle read as .Value. Use .Checked.
• Modern Toggle caption set with Text. Use Label.
• Modern Toggle initial state set with Default in this guide family. Use Checked.
• Multi-select Combo box preselection with Default. Use DefaultSelectedItems.
• Modern Dropdown with table-shaped Items but no explicit ItemDisplayText.
• ModernDropdown.Default built as a hand-constructed With({_v: ...}, {Value: _v}) literal record — no visible pre-selection on load, even with a real matching value and no PA2108 error. This is the documented fix for the Value/Value1 collision (see the entry below), and it avoids the paste-time error, but the resulting bare {Value: "..."} record apparently isn't always recognized as "the selected item" by the control at render time — the dropdown just shows blank/placeholder despite a legitimate underlying value. Confirmed: Policy Tracker ViewItem_1's radApproval1 ("Approved For Release By") showed empty on a record that genuinely had an approver set. Fix: use LookUp(Items, Value = targetValue) instead of constructing the record by hand — e.g. Default: =LookUp(Choices('List'.'Field'), Value = Coalesce(varRecord.'Field'.Value, "fallback")). This returns the actual matching row object from Items, guaranteeing structural equality rather than a look-alike literal. 2026-07-05.
• Escalates to a hard paste-time error (not just a silent blank), specifically when Items is a manually-built collection from an inline scalar array (e.g. ClearCollect(colOptions, ["A", "B", "C"]), done to dodge the Value/Value1 duplicate-literal collision — see the entry below). In that case a hand-constructed Default: ={Value: "A"} or a raw source field passed straight through (Default: =ThisItem.ChoiceField, or even .ChoiceField.Value) both throw "invalid formula, expected a value compatible with Items" at paste time, and any OnSelect handler reading .Selected.Value from that broken dropdown then throws a second, confusing downstream error (Patch failing with "incompatible type... expects a text type, and you're using an error type") — the second error is just the broken dropdown's Selected propagating as an error type into whatever consumes it, not a separate bug. The array-literal's column type isn't structurally identical to a hand-built record even though both look like {Value: Text} — same underlying cause as the blank-on-load symptom above, just a stricter failure. Fix is the same trick, applied on both sides: Default: =LookUp(colOptions, Value = ThisItem.ChoiceField.Value) (or = "A" for a fixed default) — always derive Default from a row pulled out of the exact same collection Items points at, never a value passed straight from the data source and never a hand-typed record literal, even when Items itself is just a local collection you built. Confirmed live: Branch Contact Groups scrManageGroups, drpEditThursdayBatch/drpNewThursdayBatch against colThursdayBatchOptions, 2026-07-24.
• Modern Dropdown Default set as a plain string. Must be a record: {Value: “...”}. A plain string causes the dropdown to appear blank on load.
• Any property copied from a similar control without checking that control's Microsoft Learn page.
• Size on Toggle@1.1.5. Toggle does not expose font-size. Confirmed PA2108 in live editor 2026-06-20.
• FontWeight on ModernButton@1.0.0. Modern Button does not expose FontWeight. Confirmed by cross-check against user's working Screens.txt (which uses BasePaletteColor, Color, Size but never FontWeight) 2026-06-20.
• Radius properties (RadiusTopLeft, RadiusTopRight, RadiusBottomLeft, RadiusBottomRight) on Label@2.5.1 OR Rectangle@2.3.0 — neither exposes them. Confirmed PA2108 twice: Label 2026-06-23, and again on both Label and Rectangle 2026-07-04 (Policy Tracker Main_1 issue #7 — repeated the exact same mistake the Bible already documented, on nine separate controls in one file, because the file wasn't re-checked before writing). Verified alternatives, both confirmed real: Classic/Button@2.2.0 (DisplayMode: =DisplayMode.View, Text: ="", radius on the button itself — the original documented fix, best for pure shapes/dots with no text) or ModernText@1.0.0 (supports RadiusTopLeft etc. natively per Microsoft's modern-control docs, and already used live in this exact app's Main.yaml for pill-style badges — best when the element is text-bearing, e.g. a coloured pill label). Before writing ANY new screen YAML with rounded corners on something that looks like a Label or Rectangle, grep this exact rule first — don't re-derive it from scratch or guess.
• Light or pastel BasePaletteColor on ModernButton. Fluent 2 overrides it with a dark fill. Use dark, saturated colours only.
• Conditional BasePaletteColor on ModernButton (e.g. If(varTab="X", lightColour, darkColour)). The light state always renders dark. Use Classic Button for any conditional colour states.
• Color override on a ModernButton to compensate for a wrong BasePaletteColor. Pick a darker seed instead.
• Trying to match an exact brand hex on a ModernButton. Work with Fluent 2 — pick the closest dark seed and let the framework derive the final shade.
• Text: = (bare, nothing after the equals) in YAML. Must be Text: =””.
• Bare PropName: = (nothing after the equals) is not unique to Text — it breaks the same way on ANY property, and it recurs on third-party/external component YAML, not just hand-authored screens. Confirmed 2026-07-25 auditing 23 components pasted from powerappsui.com: 13 of 23 files had at least one bare Default: = on a component's PropertyKind: Event custom-property definition (e.g. OnBarClick, OnSave, OnRowSelect), 2 files had a bare OnSelect: = on an actual Gallery@2.15.0 control instance, and several had bare LayoutMaxHeight/LayoutMaxWidth/Height/Width on real controls. A generic YAML parser (PyYAML) chokes on all of these with could not determine a constructor for the tag 'tag:yaml.org,2002:value' — a bare = is YAML 1.1's reserved "default value" tag, not a normal scalar — so this is a genuine syntax defect, not just a Power Apps quirk, and it will very likely fail paste in Studio the same way Text: = does. Before trusting any pasted-in component YAML (from a library, a doc site, an export, anything not hand-typed against this Bible), grep it for : =\s*$ (property name, colon, equals, then nothing) across every property, not just Text. Fix depends on the property: Event Default → =false (inert placeholder, Events don't need a meaningful default); a real behavior formula like OnSelect on a control instance → =false (no-op) or the actual intended formula if recoverable; a sizing property (Width/Height/LayoutMaxWidth/LayoutMaxHeight) → check whether AlignInContainer: =AlignInContainer.Stretch or AutoHeight: =true already governs that axis (if so, just delete the bare property, it's redundant) — otherwise DO NOT guess a pixel number; deleting the property (letting the axis go uncapped/unset) is safer than fabricating a value, since omission is normally a valid, common state for these properties elsewhere in the same file. Full detail: external/powerappsui/README.md and each affected component's own "Bible Audit" section.
• LayoutOverflowY on a ManualLayout GroupContainer causes PA2108 (“Unknown property 'LayoutOverflowY' for control type 'GroupContainer@1.5.0' and variant 'ManualLayout'”). LayoutOverflowY is only valid on Variant: AutoLayout containers. If you need a scrollable region in a ManualLayout screen, wrap the scrollable content in an inner AutoLayout GroupContainer with LayoutDirection: Vertical and LayoutOverflowY: =LayoutOverflow.Scroll. Confirmed: ViewItem V2.1 conForm (495,13).
• Any YAML property value that contains : (colon-space) must use a |- block scalar. If a formula like =UpdateContext({locFoo: true}) is written inline, YAML parses the {locFoo: true} as a mapping and throws YamlInvalidSyntax: While scanning a plain scalar value, found invalid mapping. This applies to any inline formula containing {key: value}, record literals, or any colon-space sequence. Always use |- for these. Confirmed: ViewItem V2.1, OnSelect: =UpdateContext({locDisplayDeletePopUp: true}) at (363,66).
• HtmlText (and any non-event-handler property) with inline CSS or other : in the string literal. |- is NOT allowed on HtmlText (PA1001) — so the |- rule above cannot apply. Instead, wrap the entire YAML value in single quotes and escape any literal single quotes inside by doubling them (''). Example: HtmlText: '="<div style=""border: 1px solid red;"">..."' where a 'Open Sans' font reference becomes ''Open Sans''. The YAML parser then treats the content as a quoted scalar and never sees the : as a mapping separator. Confirmed: ViewItem V3.5, HtmlText with CSS properties (border: 1px, padding: 14px, font-family: 'Open Sans') at (1205,56).
• %QUALIFIED_DATACARD_FIELD_VALUE.ID% in a Form card Default. This is a broken placeholder — replace with the actual field expression, e.g. ThisItem.DateCompleted.
• YAML properties on a control generated from the guide's intent without running an audit against verified-control-reference.md. Always audit before publishing.
• FillPortions: =1 (or any value >0) on a fixed-height container inside a Variant: AutoLayout parent — the "Flexible height" toggle in the property panel. A child with FillPortions > 0 grows to claim a share of the parent's remaining main-axis space, ignoring its own Height property entirely — this is the AutoLayout equivalent of CSS flex-grow, not a hint. Confirmed: Policy Tracker ViewItem_1 — conTopBar1, conWarningBar1, conCompactStepper1 and other fixed-height (64/64/44px) containers rendered many times taller than authored because "Flexible height" was ticked (FillPortions: =1) instead of off (FillPortions: =0). Symptom: a ManualLayout or AutoLayout container with an explicit Height renders drastically oversized when placed inside a vertical AutoLayout stack, while sibling containers with actual FillPortions: =1 correctly expand to fill remaining space. Fix: set FillPortions: =0 (or omit the property, if 0 is the default in this control version) on every container that must hold to its authored fixed Height; reserve FillPortions: =1+ only for the one container genuinely meant to stretch and fill the leftover space (e.g. a scrollable body region below a fixed header). Do not confuse this with AlignInContainer: Stretch — that only affects cross-axis sizing (width, in a vertical layout) and was tried first as a fix here; it didn't address the actual bug, which was the main-axis (height) FillPortions setting. Check FillPortions before AlignInContainer when a container renders the wrong height in an AutoLayout stack. 2026-07-05.

Power Fx

• ScreenTransition.Back. Use Back() or a valid ScreenTransition enum.
• Strict = false checks on SharePoint Yes/No fields inside filters can exclude blank/unticked rows. Confirmed live on Policy Tracker NewsletterPack, 2026-08-13: two newsletter items had the right Thursday date, real ACOS approval, and Published = false, but did not enter colNewsletterPack because the consultation Yes/No field failed the strict check 'External consultation required' = false. The business rule was still correct — consultation-ticked items must stay out — but the formula needed to treat blank as unticked. Use Coalesce('External consultation required', false) = false for SharePoint Yes/No gates where blank should count as false. Do not "fix" this by removing the gate unless the user explicitly changes the business rule.
• Relying on Navigate() ordering to prevent one-frame UI flashes while clearing old-screen state. Confirmed live on Policy Tracker ViewItem, 2026-08-13: moving Navigate(Main, ...) before Set(varSelectPolicy, "Empty") in btnClose1.OnSelect did not stop the amber 10-day warning banner flashing, because Power Apps can still evaluate the old screen while statements after Navigate() run. Fix: add an explicit close/navigation guard such as varClosingViewItem; set it true before clearing state or navigating on every close/discard path; add !Coalesce(varClosingViewItem, false) to any warning/header visibility formulas that must stay stable during exit; reset the guard in the destination/opening screen's OnVisible. Do not treat statement order around Navigate() as a visual synchronization guarantee.
• Immediate Navigate(...) guard inside a screen's own OnVisible. Confirmed on Training Tracker scrAdminDash, 2026-07-29: If(!varIsAdmin, Navigate(scrMyTraining, ScreenTransition.None)); in scrAdminDash.OnVisible produced Studio's error that Navigate cannot be used there because it would automatically always navigate away from the screen. Fix: remove the immediate OnVisible navigation line and guard the entry point instead, for example make the Admin button visible only when varIsAdmin is true. If a fallback redirect is still needed, use a delayed pattern only after testing in the live editor.
• Set(varName, Blank()) as the only or first-encountered assignment for a global variable. Throws No type found for variable 'varName'. Ensure that it is Set to a non-Blank value somewhere in the app — even if the same variable genuinely is set to a real typed value elsewhere (e.g. Set(varName, someTextExpression)). Power Fx's type inference isn't reliably finding the typed assignment first. Fix: replace Blank() with a properly-typed empty value that matches the real assignment — "" for Text, not Blank(), at every call site for that variable (reset/clear points, not just the first one). Confirmed: Policy Tracker ViewItem_1's varLinkDisplayNamePrefill (also set to varFileName, a Text value, elsewhere) — 6 separate Set(..., Blank()) call sites all needed changing to Set(..., ""). 2026-07-05.
• Char(n) where n is outside 1–255. Power Fx's Char() maps to the legacy single-byte/ANSI range only — it is NOT a full-Unicode String.fromCharCode equivalent, despite looking like one. Throws the runtime error The first argument to the 'Char' function must be between 1 and 255. for any codepoint above that, including extremely common ones like • (U+2022 = 8226), ◦ (U+9702... actually U+25E6 = 9702 decimal), and → (U+2192 = 8594). Confirmed live on Policy Tracker NewsletterPack's Thursday Batch email buttons, 2026-08-15 — Char(8226)/Char(9702)/Char(8594) used for bullet/arrow characters in an HTML email body all threw this error at click time (Layer A/payaml-validate does NOT catch this — it's a runtime-only error, not a paste-time syntax error). Fix: for any character above codepoint 255, embed the literal Unicode character directly in the Power Fx string literal instead of calling Char() — string literals support raw Unicode natively, no function needed ("Westminster → Resource Centre" not "Westminster " & Char(8594) & " Resource Centre"). Char() is only appropriate for genuine low-range control/ASCII characters like Char(10) (linefeed).
• Editing a formula in Studio does not re-run it. OnVisible, App.OnStart, and similar lifecycle formulas only execute when their trigger condition actually happens (screen navigation, app start) — pasting a corrected formula over an old one does not retroactively re-execute it or rebuild any variables it sets. If a bug lived inside OnVisible and got fixed, any variable that OnVisible set is still holding the OLD broken value until the screen is genuinely revisited (navigate away and back) or — safest — a full Preview restart (Esc out, Play again). Confirmed recurring pattern: Branch Contact Groups' varIsMaintainer (2026-07-24) and Policy Tracker NewsletterPack's varNewsletterBodyLead/varNewsletterBodyStatic (2026-08-15, the Char() fix above) both produced "I pasted the fix but I'm still getting the same error" reports that were actually stale session state, not a bad fix. When a user reports a fix "not working" right after pasting it, ask whether they did a full Preview restart before assuming the fix itself is wrong — especially for anything living in OnVisible/OnStart or a Refresh-button formula that duplicates it.
• Bare Ascending or Descending. Use SortOrder.Ascending or SortOrder.Descending.
• Bare Days, Months, Years etc. or TimeUnit.Days as the unit argument to DateAdd/DateDiff. Always use quoted strings: ”Days”, ”Months”, ”Years”. Confirmed broken in live builds (Training Tracker + Policy Tracker + Branch Contact Groups — recurred here despite already being documented, so double-check this specific rule every time DateDiff/DateAdd is written, not just on first use).
• Schema-less [] where Power Apps must infer collection shape.
• AddColumns(table, "ColumnName", formula) with a quoted string for the new column name argument. The column name must be a bare identifier: AddColumns(table, ColumnName, formula). This rule applies only to the column name — other string arguments in the same formula (e.g. "Days" in DateAdd) remain quoted as normal. Confirmed in Overview build. The same rule applies to GroupBy(table, "ColName", "GroupColName") — both column-name arguments must be bare identifiers too (GroupBy(table, ColName, GroupColName)). Confirmed broken in Branch Contact Groups (colPeople build, Thursday-batch grouping) — quoting them didn't error at paste time, it silently produced a table without the expected field names, breaking every downstream reference with "Name isn't recognized"/"Email isn't recognized" style errors far from the actual bug. 2026-07-23.
• LookUp(table, condition1, condition2) with more than one comma-separated condition. Unlike Filter, LookUp's signature is LookUp(Table, Formula, [ResultColumnOrReducerFormula]) — a second comma-separated argument is NOT ANDed with the first, it's evaluated as the ResultColumn/reducer formula for the matched row. If that second argument is itself a boolean comparison (e.g. Lower(Email) = Lower(varEmail)), LookUp returns a Boolean, not the matched record — silently, with no error at the LookUp call site itself. The error only surfaces later, at every place the caller tries to treat the result as a record (.Title on it throws "The dot operator cannot be used on Boolean values"; passing it to Remove()/Patch() throws "cannot use a non-record value in this context" / "incompatible type"). Fix: combine all conditions into one predicate with && — LookUp(table, condition1 && condition2). Confirmed in Branch Contact Groups scrManagePeople Save-changes handler (existing variable). 2026-07-23.
• Gallery row index formulas. Use ThisItem.ItemIndex — it shifts when the gallery filters or sorts.
• ThisItem.ID inside collection-backed galleries unless the collection explicitly contains ID.
• Switch()/If() used inside a Filter()'s predicate against a SharePoint data source — silently breaks delegation and gives wrong/inconsistent results, even though the identical set of conditions works fine when Switch instead picks between whole separate Filter() calls. This app's own HeaderGallery.Items already does it the safe way (Switch(varSelectedState, "Current", Sort(...Filter('Policy Proof Tracker', conditionA)...), "Future", Sort(...Filter(..., conditionB)...), ...) — one plain-boolean Filter per branch, Switch only ever chooses which whole expression to run). A per-chip live-count formula instead put Switch(varSelectedState, "Current", condA, "Future", condB, ...) && ownerCond && typeCond as the single predicate passed to one Filter() call — same conditions, wrong shape. Confirmed live on Policy Tracker Main: chip counts summed to 25 with the "Issues" tab selected, while that tab's own real item count was 0, which is only possible if the count formula wasn't actually gating on the tab at all. Fix: never nest Switch/If inside a single Filter's predicate against a delegable data source — expand it inline as (state = "X" && condA) || (state = "Y" && condB) || ... instead, matching the shape every other working Filter in this app already uses. 2026-07-06.
• Nested formulas that rely on ambiguous ThisItem; capture the row with With or use As aliases.
• Referencing an outer AddColumns row identifier (e.g. Value from Sequence) inside a nested Filter predicate. Inside Filter(innerTable, predicate), the predicate is evaluated with innerTable's row scope. If innerTable doesn't have a Value column the identifier falls through, but if there's any ambiguity PowerApps resolves it to blank — making DateAdd(varBase, (Value-1)*7, "Days") evaluate to the same date for every row. Always use With to capture outer-scope identifiers before entering the Filter: With({weekDate: DateAdd(varBase, (Value-1)*7, "Days")}, Filter(innerTable, DateField = weekDate)). Confirmed: all 4 Overview columns showed identical data because Value inside the nested Filter was blank, computing the same date for all 4 columns. 2026-06-25.
• A nested Gallery's Items property cannot evaluate the outer gallery's ThisItem. The Items formula of a child gallery is evaluated at screen scope, not template scope — so ThisItem.Column in galWeekItems.Items is always blank regardless of whether the gallery is inside a GroupContainer or a direct child. Labels and other non-gallery controls DO correctly resolve ThisItem in their properties. The correct pattern: pre-compute the inner data as a column in the outer gallery's Items formula using AddColumns, then set the inner gallery's Items = ThisItem.PreComputedColumn. This is the same pattern as galHeaders → ThisItem.GroupedItems in Main.yaml. Always collect the source data into a local collection first (ClearCollect(colName, Filter(...))) so the Filter inside AddColumns runs client-side. Confirmed: all four failure modes tested in Policy Tracker Overview 2026-06-24/25.
• Bare DisplayMode=View. Use DisplayMode=DisplayMode.View or set the property value to DisplayMode.View.
• DisplayMode: =DisplayMode.View on a Classic/Button that also has a real OnSelect — no paste-time error, no visual clue, the tap just silently does nothing. Per Microsoft's own docs, View mode means the control "cannot... otherwise interact with it" — for a Button that disables the click entirely, not just its hover/pressed styling. This app family has a long-standing convention of setting DisplayMode.View on invisible/decorative Buttons used as tap-target overlays or coloured backgrounds (to suppress the default blue hover/press flash) — that's fine and correct for controls with no OnSelect (recCardFrame, recHeader, recCreatePanelBg, etc.), but it silently kills the control for the ones that DO have OnSelect. Confirmed live 2026-07-24 on Branch Contact Groups: recResultTap (GAL search result row — user reported "clicking on it does nothing"), plus 3 more found by grepping the same pattern before the user hit them one at a time: recCheckBox (scrSendEmail), recPersonRowFrame (scrManagePeople), and recLightboxBackdrop on all three screens (click-outside-to-close). Fix: never combine DisplayMode: =DisplayMode.View with OnSelect on the same Button — just omit the DisplayMode line entirely; Fill/HoverFill/PressedFill alone already give full control over the visual appearance without disabling the tap. Before shipping any new invisible-overlay-button pattern, grep the screen for DisplayMode.View and OnSelect both appearing on the same control — this is exactly the kind of bug that hides for a long time because it never throws an error and the control still renders correctly, it just doesn't respond to the one interaction that matters.
• Correction, 2026-07-24 same incident, recResultTap/recRowFrame: a follow-up scrub can still miss one if the OnSelect was added to the control after the original scrub ran (which is exactly what happened here — recRowFrame had no OnSelect at scrub time, so the grep for "View + OnSelect" didn't catch it; OnSelect was added in a later pass without re-checking for a leftover DisplayMode.View). Whenever adding a new OnSelect to an existing control, always check/remove any pre-existing DisplayMode.View on it in the same edit — don't treat "add OnSelect" and "remove stale DisplayMode" as two separate, independently-forgettable steps.
• A lightbox's backdrop/panel Buttons declared AFTER their own content controls in the children list — the panel's opaque Fill renders in front of everything, so the lightbox appears completely empty (just the title and close icon, if those happen to be declared even later than the panel). Z-order in this app's YAML is simple list order — later children render in front of earlier ones — so a lightbox's recLightboxBackdrop/recLightboxPanel must be declared BEFORE all of that lightbox's content controls, not after. Confirmed live 2026-07-24 on Branch Contact Groups scrManagePeople: the backdrop/panel/title/close block sat near the very end of the children list (after Add Person, Edit Person, and Purge fields), so every one of those fields was hidden behind the opaque white panel — only the title and close icon (declared even later, so in front of the panel too) were visible. This was a pre-existing bug from before that day's changes, not introduced by whatever was being added at the time — it simply hadn't been exercised/noticed yet. scrManageGroups and scrSendEmail already had the correct order (backdrop/panel/title/close declared first, all content after) from the start, which is why they never showed this symptom. When building or auditing any lightbox, check that recLightboxBackdrop/recLightboxPanel are the FIRST children declared for that lightbox, not the last — an empty-looking lightbox (title/close visible, everything else blank) is the exact signature of this bug.
• A row's click-catcher Button sitting in front of its own text Labels, with a real (non-transparent) HoverFill set for a hover highlight — the text visibly disappears on hover, replaced by a solid-coloured rectangle. If a Button needs to both catch clicks (so it must sit in front of overlapping Labels, per the entry below) and show a hover highlight, combining both jobs into one control is a trap: its opaque HoverFill renders on top of the Labels the instant the mouse moves over it, since it's in front of them. This isn't a colour-contrast problem — the text isn't just hard to read, it's fully covered. Confirmed live 2026-07-24 on Branch Contact Groups: recResultTap (GAL search result row, scrManageGroups) had HoverFill: =RGBA(233,241,246,1) and sat after lblResultName/lblResultEmail in the children list (i.e. in front of them) — hovering any result row made its name and email vanish completely under the pale blue rectangle. Fix: split hover-highlight and click-catching into two separate controls — a decorative highlight rectangle at the very back (DisplayMode.View, no OnSelect, its HoverFill is the real highlight colour) sitting behind the Labels, and a separate, fully transparent click-catcher (HoverFill: =Self.Fill, i.e. never visually changes) sitting in front of the Labels holding the real OnSelect. This is the same "background → labels → transparent click-catcher → distinct-action controls" ordering already established for click-passthrough — just add the highlight rectangle as a fourth layer at the very back, before everything else.
• A background click-target Button under overlapping Labels — clicks only register on the blank margins, not on the visible text itself. Once a full-size background Button has a working OnSelect (see entry above), any Label layered on top of it for visible text (name, meta line, notes, etc.) still blocks the tap from reaching it — a control fully occupies its own space for hit-testing regardless of whether it has its own OnSelect, so Labels do not let clicks pass through to whatever's behind them. Don't fix this by duplicating the same OnSelect onto every overlapping Label — fragile, easy to miss one (tried and explicitly rejected by the user on Branch Contact Groups 2026-07-24: "I can't believe there's no smart way around this"). Correct fix: add ONE separate, fully transparent Button (Fill: =RGBA(0,0,0,0), BorderThickness: =0, no text) positioned in front of the Labels but behind any small control that needs its own distinct action (a checkbox, an icon) — transparent, so nothing is visually hidden; in front of the Labels, so it catches every tap regardless of where the text sits; behind the small distinct-action controls, so they keep working independently. Z-order in this app family's YAML is simple ordering — later children render in front of earlier ones — so the required order is: decorative background → Labels → transparent click-catcher → any small distinct-action controls last. Confirmed live: Branch Contact Groups recRowClickCatcher (scrSendEmail, sits in front of recRowFrame/labels, behind recCheckBox/icoViewMembers/icoViewHistory) and recPersonRowClickCatcher (scrManagePeople, no other distinct-action controls in that row so it's simply frontmost).
• \xB7 or any \x escape sequence in Power Apps strings. Use Char(decimal) instead. Middle dot is Char(183).
• IsOdd() — does not exist in Power Apps. Use Mod(value, 2) = 1.
• SortByColumns on a SharePoint Choice field. Use Sort(..., Field.Value, SortOrder.Ascending) to unwrap the Choice record.
• ”value” in MultiChoiceField for multi-select Choice filtering. Use CountIf(MultiChoiceField, Value = “value”) > 0.
• Launch(url) without LaunchTarget.New — reuses current tab. Use Launch(url, {}, LaunchTarget.New).
• ScrollTo(gallery, item) in screen OnVisible or any behavior formula. ScrollTo is not universally supported in canvas apps — confirmed "unknown or unsupported function" in live build (Policy Tracker). Remove it entirely; restore scroll position via Navigate to the screen instead, or accept the gallery always resets to the top.
• SortByColumns(AddColumns(table, "SortKey", formula), "SortKey", ...) pattern inside a nested gallery's Items property (where table = ThisItem.GroupedItems). The dynamically added column is not reliably resolved by SortByColumns in this context — confirmed error "column 'SortKey' does not exist" (Policy Tracker). Use Sort(ThisItem.GroupedItems, formula, SortOrder.Ascending) instead, referencing fields directly by bare name inside the formula.
• Referencing a SharePoint field in YAML that has not been confirmed to exist in the list. Before using any field name in card/form YAML, verify it is in the live SP list. Confirmed error when Status.Value was used but the SP list only had Published (boolean) — Policy Tracker.
• ForAll(cmbControl.SelectedItems As T, {Value: T.Value}) for patching multi-select Choice. Prefer ForAll(cmbControl.SelectedItems, {Value: Value}) — the alias form can cause type mismatches.
• Assuming Default/DefaultSelectedItems re-evaluates reactively when the source variable changes after the control already exists. It doesn't — confirmed via Microsoft's own Reset() function docs and multiple community threads: these properties are read once, at control creation, to seed the initial value. If a screen sets varSelectedRecord (or similar) in OnVisible and expects an already-rendered dropdown/combobox/checkbox to pick it up, it won't — the control was created before (or in the same tick as) the variable being set, so it captured whatever value existed at that moment (often blank). Fix: explicitly Reset(controlName) for every Default-driven input, at the very end of OnVisible, after all the data-loading Sets/ClearCollects have run. This applies to ModernDropdown.Default, ComboBox.DefaultSelectedItems, Classic/CheckBox.Default, DatePicker.SelectedDate when treated as an initial value, etc. — not just Modern controls. Confirmed: Policy Tracker ViewItem_1 — drpDocType1, radApproval1, cmb_Owner1 all showed blank/unselected on a record with real data, even after fixing the Default formula itself (see the LookUp entry above) — the formula was correct, the control just never re-read it. 2026-07-05.
• Same root cause, different shape — it also happens INSIDE a Gallery, per-row, not just for a single shared control. A Gallery can recycle its child control instances across an Items refresh (e.g. ClearCollect) rather than fully destroying and recreating them, especially when the row count doesn't change — so a checkbox's Default bound to ThisItem.Picked (or similar) can silently keep showing whatever it captured the FIRST time that row-instance was created, even though the underlying collection now has genuinely different Picked values for a newly-selected record. Symptom: the checklist visually renders correctly (right group names, right count) but nothing is ever ticked, no matter what the real membership data says — easy to misdiagnose as "the box is too small, the ticked ones are scrolled out of view" (a wrong theory tried first here) since the visible SYMPTOM looks identical to a scroll-visibility problem. Confirmed live 2026-07-24, Branch Contact Groups scrManagePeople chkGroupMember/colPersonGroupPicks — persisted even after enlarging the checklist from 180px to 320px, which is what disproved the scroll theory and pointed at this instead.
  • First attempted fix, also wrong, and worth recording because it produces a distinctive visible error banner: Reset(controlName) called from OUTSIDE the gallery that control lives in. This is not legal Power Fx — a gallery template's child controls can only be Reset() from within a formula written inside that same gallery template, never from a button/OnSelect elsewhere on the screen. The runtime error is exactly this text: "The Reset function can only be used with a resettable control. Controls within a Form or Gallery control can only be reset from within the same form or gallery template." If you see that banner, the immediate cause is always a Reset() targeting a gallery-child control from the wrong scope — remove it, don't try to relocate it into a different outside caller, it can't legally be called from anywhere outside that gallery.
  • Real, confirmed fix: convert the checkbox from Classic/CheckBox@2.1.0 (one-shot Default) to CheckBox@0.0.30, the Modern Checkbox, using Checked instead of Default. Checked is genuinely reactive — it re-evaluates on every render, the same way any other Modern-control formula-bound property does (Visible, Text, BasePaletteColor, etc. all already behave this way elsewhere in this app family) — so it correctly reflects the collection's current Picked value for whichever record is now selected, with no Reset() of any kind needed anywhere. This sidesteps the whole "does Default re-read" question entirely rather than fighting it. Confirmed live 2026-07-24 same incident, chkGroupMember/chkAddPersonGroup.
• EXCEPTION — do not call Reset() on ModernCombobox. Microsoft's own changelog for this control states: "Reset() includes SearchText: The Reset() function now clears both the selection and the search text." For this control specifically, Reset() was changed to also blank the selection — it does not just restore DefaultSelectedItems the way Reset() does for every other control. Confirmed: Policy Tracker ViewItem_1's cmb_Owner1 had a correctly-computed DefaultSelectedItems (set earlier in the same OnVisible, in the right order) that was then immediately wiped back to blank by the screen's own Reset(cmb_Owner1); call, applying the general advice above. Fix: skip Reset() for ModernCombobox controls entirely — if DefaultSelectedItems is set before the control is created (i.e., earlier in the same OnVisible/before first render), it doesn't need a Reset() nudge the way Default-driven controls do. 2026-07-05.
• Notify-first validation pattern (checking fields then calling Notify before running Patch). Use Set-error-vars-then-If-guard pattern instead.
• Calling Reset(Self) inside a control's own OnChange, when that control's value property is itself bound to a live formula (e.g. DatePicker.SelectedDate: =varSelectedRecord.Field). Reset() forces the control to re-run its bound formula immediately — which just puts back the old/blank value, silently destroying whatever the user just picked. This was being used as an ad-hoc validation trick ("if the picked date isn't a Thursday, reset it") but it fires on every non-matching pick, not just invalid saves, so it reads as "the field randomly clears itself" rather than a deterministic rule. Confirmed on Policy Tracker ViewItem's dpkPublishDate1: any non-Thursday click silently reverted to varSelectedRelease.'Planned Publish Date'. Fix: never Reset(Self) for input validation on a formula-bound value control. Just Notify() the warning (the invalid value stays visible/selected) and enforce the real rule at Save time instead, e.g. gate the Save button's validation on Weekday(control.SelectedDate, StartOfWeek.Monday) <> 4 so a bad value blocks the save rather than getting silently erased before the user even reaches Save. 2026-07-06.
• Set() on a global variable from inside ForAll — Studio now blocks this outright: "This function cannot be invoked within ForAll." This is a real, current Power Apps platform restriction, not a formula mistake — ForAll iterations aren't guaranteed to execute in strict sequence, so Microsoft disallows mutating global state from inside the loop to avoid race conditions. This most often shows up in an accumulator pattern, e.g. counting failures from a per-row IfError inside a bulk ForAll(Patch(...)) loop: IfError(Patch(...), Set(varFailCount, varFailCount + 1)) errors on the Set(...) line specifically. Fix: Collect() into a fresh collection instead — Collect writes are still allowed inside ForAll, each iteration just appends its own row independently, so there's no ordering dependency. Then set the variable ONCE, from CountRows(collection), after the ForAll has finished (this is fine, it's no longer inside the loop): Clear(colFailures); ForAll( source As Row, IfError( Patch(...), Collect(colFailures, {ID: Row.ID}) ) ); Set(varFailCount, CountRows(colFailures)); Confirmed live: Policy Tracker Main.yaml's PublishAllBtn.OnSelect — the original per-row Set(varPublishFailCount, varPublishFailCount + 1) inside the ForAll/IfError threw this exact error on paste into Studio. 2026-07-22.
• Follow-on error after applying the Collect() fix above: IfError(Patch(...), Collect(...)) throws "Invalid argument type (Table). Expecting a Record value instead." Patch(...) returns a Record (the patched row); Collect(...) returns the whole Table it just collected into. IfError's two branches (the normal-path value and the error fallback) must resolve to the same type, and Record vs Table doesn't unify. Fix: end both branches with ; true, so each side evaluates to a plain Boolean instead of its natural Patch/Collect return value — a statement chain's type is just whatever its last statement evaluates to, so appending ; true sidesteps the mismatch entirely without changing behavior: IfError( Patch(...); true, Collect(colFailures, {ID: Row.ID}); true ) Confirmed live: same PublishAllBtn.OnSelect, immediately after the Set-in-ForAll fix above, same session, 2026-07-22. When pairing IfError's success/fallback branches, always check that both sides' final function call returns the same type (or force it with ; true) — don't assume any two working single-purpose calls (a Patch here, a Collect/Remove/etc. there) are automatically compatible as IfError siblings.
• & cannot concatenate two tables — it's the text/scalar concatenation operator only (accepts Text/Number/Date/Time/DateTimeNoTimeZone/DateTime/Boolean/ViewValue/Dynamic — that exact list is what the error names). Table({...}) & existingCollection throws "Invalid argument type. Expecting one of the following: Text, Number, Date, ..." because Power Fx is trying to coerce both tables down to a scalar for &, not concatenating them as tables. To prepend/append a record to an existing collection, don't try to build the combined table in one formula — mutate the collection itself: ClearCollect(coll, {newRow}) then Collect(coll, ForAll(source, {...})) (or just Collect(coll, {newRow}) if not rebuilding from scratch). Confirmed on Policy Tracker Main, trying to inject a synthetic "All types" chip row ahead of colChoiceColors for a type-filter gallery. 2026-07-06.
• In the browser editor's manual Insert-panel workflow (not YAML paste), LayoutDirection and LayoutGap are not settable via the property formula bar at all, even though both are completely valid, working GroupContainer@1.5.0 YAML properties (confirmed throughout this app's exported YAML — DashboardContainer, ScreenContainer1, etc. all use them). The Insert panel exposes three distinct container choices — Container (blank/ManualLayout), Horizontal container, Vertical container (both AutoLayout) — and picking one fixes the direction permanently at creation time; there is no property in the formula-bar "add property" list to change it afterward. Gap between children is set via a dedicated Gap stepper control in the properties pane (next to the alignment icons), not a formula. Every other AutoLayout property (Fill, Height, Width, padding, DropShadow) is a normal formula-bar property — only direction and gap are insert-time/UI-only. When writing a guide for someone building manually in the browser (as opposed to a YAML paste), say "insert a Horizontal/Vertical container" and "set Gap via the properties pane stepper" — never "set LayoutDirection/LayoutGap via formula." Confirmed by direct user correction on Policy Tracker Main, 2026-07-06.
• The confirmed real YAML property name for "wrap children to a new row" on a Variant: AutoLayout GroupContainer@1.5.0 is LayoutWrap (boolean, e.g. LayoutWrap: =true) — this is settable via the formula bar, unlike LayoutDirection/LayoutGap above. Confirmed live in Policy Tracker Main's TypeFilterBar export. Don't hedge this one as "check the properties pane" the way LayoutDirection/Gap need to be — LayoutWrap is a normal property.
• Manual X/Y properties on a control whose immediate parent is Variant: AutoLayout are unreliable/likely ignored — AutoLayout positions children by flow order (plus padding/gap/alignment), not by coordinates. Confirmed the hard way: a guide gave explicit Y values for Title inside Container5 (an AutoLayout LayoutDirection.Horizontal container), and the user's real, working, live-tested build left Title.Y completely unchanged from its pre-AutoLayout value — changing it had no visible effect, exactly as it would if the property were being ignored. Only give manual X/Y instructions for controls whose direct parent is Variant: ManualLayout. For a control inside an AutoLayout parent, describe the change in terms of order/alignment/padding/gap instead, or explicitly flag "this parent is AutoLayout, X/Y may not apply — verify live." Policy Tracker Main, ReleaseGallery card thinning, 2026-07-07.
• A screen-level equivalent was suspected but NOT confirmed in one build (see the Scale to fit entry below, which turned out to be the actual cause that time) — don't assume a screen has an "Auto layout" toggle without seeing it live. Some Studio versions/app types have no such screen-level setting at all; the Properties panel for a screen may only expose Fill/BackgroundImage/LoadingSpinner/Height with nothing resembling a layout-mode toggle. If a screen's controls all bunch together regardless of their authored Y values AND regardless of Screen.Height, check Scale to fit (App settings → Display) before concluding it's an AutoLayout screen.
• App setting Scale to fit (App settings → Display, ON by default in most templates) proportionally shrinks an entire screen's rendered content to match the actual device viewport, regardless of that screen's own Height/Width property. This means increasing a screen's Height to make it scroll does nothing if Scale to fit is on — the runtime just scales the whole layout down harder to keep cramming it into the same fixed frame, so controls with very different authored Y values (e.g. Y=750 vs Y=1470) end up rendered close together, visually indistinguishable from an overlap/AutoLayout bug. Symptom: making a screen taller has zero effect on spacing — everything stays visually bunched at whatever size, "it doesn't matter how big I make it." That's the tell it's Scale to fit, not AutoLayout and not a too-short-canvas problem. Fix: App settings → Display → turn off Scale to fit (and Lock aspect ratio if present) — only then does increasing a screen's Height beyond the device viewport make it genuinely scroll instead of scale. Suspected (not yet live-confirmed) in Branch Contact Groups scrManageGroups — the "Manage Members" panel (12+ controls, authored Y=750 to Y=1514) stayed bunched together after raising Screen.Height alone; ruled out a screen-level AutoLayout toggle first since the user's Properties panel had no such option. Update this entry to CONFIRMED once the user verifies Scale to fit was actually the fix. 2026-07-23.

Power Automate

• A "Power Apps (V2)" trigger input passed as Text (or any wrong type) when the downstream action's field expects a different type — the dynamic content picker on that field silently shows "No dynamic content available," with no error, indistinguishable from a genuinely broken/stuck picker. Confirmed against Microsoft's own troubleshooting docs, not guessed: the dynamic content picker filters its suggestion list by matching the target field's data type — a Number-typed field (e.g. Id on any SharePoint Update item/Get attachments/Delete attachment/Add attachment action) will not list a Text-typed trigger input at all, even though the value genuinely exists and other Text-typed fields in the same action show it fine. Source: Dynamic content picker missing dynamic content from previous steps, "Cause 2: Data Type Mismatch". Before building any flow that writes to a SharePoint list, check the real column type of every field you intend to target with a trigger input — SharePoint's own numeric ID (used for every Id field) is always a Number, and any other column defined as a Number/Choice/Yes-No column in that specific list needs a matching-typed trigger input, not a default Text one. Going the other direction (Number value into a genuinely Text-typed SharePoint column) is fine and does not hit this filter — SharePoint's connector coerces it automatically. Confirmed live: Training Tracker TT - Save Certificate flow, 2026-07-30 — both RecordID (targets every Id field) and CourseID (targets TT TrainingRecords.CourseID, itself a Number column) were originally specified as Text, and both silently failed to appear as dynamic content on their Number-typed target fields until switched to Number inputs.
• An unsaved Power Automate flow loses all trigger inputs on a browser refresh (F5). There is no autosave/draft-restore for a flow that has never been saved once — if you hit a wall partway through building the trigger and refresh to try to unstick the editor, you lose every input added so far and must re-add them from scratch. If a flow won't save because a downstream required field has no value yet, do not refresh to try to fix it — fill the required field with any placeholder value first (see "SharePoint list with required columns forces every Update item to resupply them" below, if that's the actual cause), get the flow to save once, then go back and fix the value properly.
• A SharePoint list with required columns forces every Update item action to resupply a value for those columns, even ones you have no intention of changing. If a list's schema marks a column as required (e.g. PersonEmail, CourseID, CourseName on TT TrainingRecords), the Update item connector action shows a red asterisk and refuses to save the flow until every required column has something in it — not just the columns you actually want to update. Fix: re-supply the existing/unchanged value from whatever the flow already has available (e.g. the same trigger input that carried it in), rather than leaving it blank or inventing a new value. This does not change the stored data, it just satisfies the connector's validation. Confirmed live: Training Tracker TT - Save Certificate flow, 2026-07-30.
• A Respond to a PowerApp or flow action cannot be nested inside an Apply to each (foreach) loop — Power Automate blocks this outright at save time with InvalidWorkflowRunAction: ... type 'Response' ... could not be nested under an action of type 'foreach'. There is no setting to allow it; the Respond action is only valid as a top-level (or Condition-branch-level) action, never inside a loop. This also means Initialize variable actions have their own placement rule: they can only run at the very top level of the flow (directly after the trigger), never inside a Condition or loop either. Fix for "fetch one file from inside a loop, then respond with it": initialize the needed variables (e.g. varFileName, varFileContentBase64) at the top level before any Condition; inside the loop, use Set variable to populate them (an action from inside a loop is otherwise an array once outside the loop, so a variable is the standard way to pull a single value back out); then place the actual Respond to a PowerApp or flow action after the loop ends, reading from the variables instead of from loop-scoped dynamic content. Confirmed live: Training Tracker TT - Get Certificate flow, 2026-07-31 — the original guide draft placed Respond directly inside the Apply to each over Get attachments, which failed to save with exactly this error.

• A flow cannot have two separate Respond to a PowerApp or flow actions at all — not even one per Condition branch with identically-named/typed outputs. This is the deeper, easy-to-miss cause behind a specific, maddening symptom: the app's formula bar (e.g. varResult.someField) only ever autocompletes a subset of the fields actually configured on the Respond action(s) — commonly just the fields that happen to be identical across every branch — with no error, no warning, and the missing fields behaving as if they don't exist even though the flow designer visibly shows them configured correctly on both Respond actions. This survives everything that looks like it should fix a caching problem — removing/re-adding the flow as a data source (repeatedly), fully closing and reopening the app, correcting field name casing, even copying the entire flow to a brand-new name via "Save As" (the copy inherits the exact same broken behaviour, because the two-Respond-action structure itself is the defect, not any cached metadata). Confirmed via a moderator-verified answer on Microsoft's own Power Platform community forum: "You can't have two Respond to Power Apps actions in the same flow." Fix: never use more than one Respond to a PowerApp or flow action in a flow, full stop. Where a flow's logic branches (e.g. an authorisation Condition), set plain variables (e.g. varSuccess Boolean, varMessage/varFileName/varFileContentBase64 String) inside each branch instead of responding from within it, then place exactly one Respond action after the branches rejoin, reading every output from those variables. Confirmed live: Training Tracker TT - Get Certificate flow, 2026-07-31 — two Respond actions (one per branch of the authorisation Condition), each configured with the same 4 outputs, still left the app only recognising success/message, across three separate remove/re-add cycles and one full flow duplication, until both Respond actions were removed and replaced with the single-Respond-plus-variables pattern.

• A Power App does not automatically pick up changes made to a flow it already calls — editing and saving an action inside a flow (e.g. fixing a field name in a Create item/HTTP action's body) has no effect on an app already referencing that flow until the app's own connection to it is refreshed. Confirmed live: a flow was edited and saved (verified via the flow's own run history showing the new action content correctly), yet a Power App calling that flow via 'FlowName'.Run(...) kept executing the old, pre-edit logic on every subsequent test — the run history for the Power-App-triggered runs still showed the old field names, not the ones just saved in the designer. Fix: in Power Apps Studio, open the Data panel, find the flow under Connections/Data sources, and refresh (remove-and-re-add, or the panel's own refresh action) that specific flow's reference — this is what forces the app to pick up the latest saved version. Do this after every flow edit that a live app is already calling, not just the first time a flow is added as a data source. Confirmed live: Library & File Plan Manager Create Library (App) flow, 2026-08-12 — a Create_FilePlan_Row body fix (renaming a broken SharePoint field) was correctly saved in the flow designer, confirmed via the flow's own Code view, yet a Power App test run still executed the pre-fix version until the app's flow connection was manually refreshed.

Architecture

• Loading collections only in App.OnStart and not reloading in screen OnVisible. Collections go stale when data is added in a different screen or session.
• Using ClearCollect(colMemberships, 'BM Memberships') as if it loads the whole SharePoint list. It only caches the first client-side page, so later membership rows never reach the app. Confirmed 2026-07-27 on Branch Contact Groups: scrSendEmail showed 0 members for groups such as CTC Frimley even though SharePoint BM Memberships had real rows. Counts and recipient generation were reading the incomplete local colMemberships collection. Fix for Branch Contact Groups v2.32: build colGroups first, then load memberships group-by-group: ClearCollect(colMemberships, Filter('BM Memberships', false)); ForAll(colGroups As grp, Collect(colMemberships, Filter('BM Memberships', GroupName = grp.Title))). This avoids the global row cap because each query only fetches one group's roster.
• Not initialising varViewingForSelf at the top of OnVisible. If it is blank, a self-view/team-view screen will show nothing.
• Hard-coding Set(varViewingForSelf, true) in a gallery row OnSelect. This breaks team-member viewing.
• Not calling ResetForm(frmCert) in a form screen's OnVisible. The form shows stale data on revisit.
• Not resetting error border variables (Set(varErrX, false)) when opening an edit panel. Red borders from a previous failed save linger.
• Assuming a field exists in varCourse because it exists in SharePoint. The field only exists in varCourse if the ForAll projection that built colMyTraining included it.
• A global collection populated with AddColumns (computing an extra field) in one place, and a plain ClearCollect/Filter (without that same AddColumns) in another. Causes a visible flicker: whichever population runs last wins, and if the plain one runs after the computed one, every row loses the computed field and any UI reading it (e.g. an icon Switch on the computed column) falls back to its default/error branch — looking like the correct data displayed briefly then "broke". Confirmed: Policy Tracker ViewItem_1 — the link gallery's file-type icons flickered from correct (PDF/Word/Excel) to a generic fallback icon on load, because the link-modal's "reload after edit" success handler computes FileExt via AddColumns, but the screen's own OnVisible repopulates the same collection with a plain Filter and no AddColumns at all. Fix: every population point for a given collection must compute the same derived columns, not just the one call site that happened to need it first. 2026-07-05.
• Recurred 2026-07-22 on the exact same collection (colLinks), a different set of call sites. This time it wasn't a flicker-on-load, it was icons resetting to the generic fallback specifically on Save/Save & Close of the parent item (not the link modal) — the item's btnSaveClose1/btnSave1 success handlers, plus the nested save-then-open-link-modal branch in btnAddLinkEmpty1, all did ClearCollect(colLinks, Filter(PolicyLinks, PolicyTrackerSource.Id = varSavedRecord.ID)) with no AddColumns/FileExt, while BuildLinksForSource (the one that runs on opening the item) correctly computes it. Closing and reopening the item "fixed" it because that re-ran BuildLinksForSource. Lesson confirmed twice now: whenever a collection's schema depends on a computed column, grep every ClearCollect/Collect call site for that collection name before trusting any single one of them is complete — this bug has now recurred by adding a brand-new population site (a Save handler) without checking the others, not by editing an existing one.
• Using Badge control to render repeating pills. Badge cannot loop over a collection — use Gallery + Classic Button.

• Any screen YAML that does not start with Screens:\n ScreenName:. The pa-yaml-wrap tool and PowerApps Studio paste both require this exact top-level format. Never use - ScreenName: (list item). Always use the dict form: Screens: at col 0, screen name at col 2, Properties: and Children: at col 4.
• Pasting a corrected screen YAML over an existing screen that already has that screen's name. Studio's paste is additive/merge, not a full replace — controls present in the old paste but removed from the new YAML (e.g. a hidden staging control that got deleted as part of a fix) can be left behind on the canvas with their old, now-orphaned bindings still intact, still capable of throwing the old error. When a fix removes or renames a control, tell the user to delete the whole screen and paste fresh into a new blank screen, not paste over the existing one. Suspected cause of a fix "not taking" in Branch Contact Groups even after confirming the source YAML no longer contained the offending control. 2026-07-23.
• GroupContainer@1.5.0 without a Variant: keyword. Every GroupContainer requires Variant: ManualLayout (or Variant: AutoLayout) between Control: and Properties:. Omitting it causes PA1011 on paste. Confirmed broken in Overview build.
• LayoutMode: =LayoutMode.ManualLayout inside a GroupContainer's Properties block. Do not set LayoutMode as a property — Variant: ManualLayout already implies it. Including it causes PA2108. Remove the property entirely.
• Gallery@2.15.0 without a Variant: keyword. Every Gallery requires Variant: between Control: and Properties:. Use Variant: Vertical for vertical galleries, Variant: Horizontal for horizontal galleries, Variant: VariableHeight for variable-height galleries. Confirmed PA1011 in Overview build.
• Layout: =Layout.Horizontal or Layout: =Layout.Vertical inside a Gallery's Properties block. Do not set Layout as a property — the Variant already implies it. PA2108 if present. Same rule as LayoutMode on GroupContainers. Confirmed in Overview build.
• Image@2.2.0 — stale. Always use Image@2.2.3. PA2105 warns it may produce errors.
• SelectedDate as a settable property on ModernDatePicker@x.x.x — do not use, in any version. Confirmed broken on both 1.0.0 and 1.0.1 in this environment: PA2108: Unknown property 'SelectedDate', identical error, same lines, after bumping the declared version (see the now-corrected theory below). Microsoft's own docs page lists SelectedDate as a real property of the control family, and it genuinely works as a read (Self.SelectedDate inside the control's own OnChange, or otherControl.SelectedDate from elsewhere) — but it is not a valid key to author in the YAML Properties: block for this control, at least not in the version(s) tested. Do not attempt a version bump as the fix (already disproven — see below). Use DatePicker@0.0.46 instead (a different, non-"Modern"-prefixed control family) — confirmed live and working in Policy Tracker's real ViewItem.yaml/ViewItem_1.yaml, which sets SelectedDate successfully on that control tag with a full property set (BorderColor, BorderStyle, BorderThickness, Fill, Font, FontSize, Format, Height, IsEditable, OnChange, SelectedDate, StartOfWeek, Width). It is not Classic-prefixed and renders with the same rounded/modern look as the rest of the app, so it satisfies "no Classic-style sharp corners" without the ModernDatePicker schema problems.
• Corrected theory (originally recorded here, then disproven): the first hypothesis was that ModernDatePicker@1.0.0's declared version was simply stale — the same paste's PA2105 warning named 1.0.1 as current, so the version was bumped to 1.0.1 expecting that to fix it. It did not; the identical PA2108 error recurred against 1.0.1. Lesson: a PA2105 version-mismatch warning appearing alongside a PA2108 unknown-property error does not mean the version bump will fix the error — they can be two independent issues. Don't assume a version bump resolves a property error without re-testing; if it doesn't, stop iterating on that control and switch to a proven alternative rather than guessing a third property name or version. Policy Tracker ViewItem_1, 2026-07-05.
• Recurred 2026-07-08, via a different path — manually rebuilding the field in the browser editor's Insert panel, not a YAML paste. dpkPublishDate1 on the real ViewItem ended up back on ModernDatePicker@1.0.1 (someone picked "Modern Date picker" from Insert instead of the plain "Date picker"), with DefaultDate instead of SelectedDate and FontWeight: =""/Placeholder (neither a real property on the Classic control). Symptom: Format: =Text(Self.SelectedDate, "d mmmm yyyy") rendered as a squashed "2 Jul26 2026" instead of "2 July 2026".
• Actual root cause, found by the user directly, not by guesswork — ModernDatePicker.Format does not support the 4-m "mmmm" token (full month name) the way DatePicker@0.0.46.Format does. With four ms, the control silently mis-renders instead of erroring — no PA error, no warning, just garbled output ("2 Jul26 2026"). Fix confirmed live: drop to three ms, "d mmm yyyy", and the exact same ModernDatePicker@1.0.1 control renders correctly ("2 Jul 2026") — no control swap needed at all. This means the SelectedDate-authoring bug earlier in this entry and the Format 4-m bug are two separate, independent problems with this control, not the same root cause — don't assume the whole control is unusable just because one specific property has a known issue; test the actual failing property in isolation (here, just the format string) before reaching for a full control replacement. Getting this wrong meant recommending a disruptive full-control swap (with a guide page and a GitHub issue reply) for a one-character fix. Policy Tracker ViewItem, 2026-07-08.
• DatePicker@0.0.46's two syntax quirks worth remembering if a control swap is ever genuinely needed for a different reason: SelectedDate (not DefaultDate) is the settable property, and StartOfWeek takes a plain quoted string (="Monday"), not the StartOfWeek.Monday enum ModernDatePicker uses.
• Tooltip on DatePicker@0.0.46 is not a valid YAML property. Confirmed by user paste error on Training Tracker scrCourseDetail DataCardValue1, 2026-07-27: PA2108: Unknown property 'Tooltip' for control type 'DatePicker@0.0.46'. Remove the property; use a nearby label/help text if the date field needs an explanation.

• There is a THIRD date picker control, Classic/DatePicker@2.6.0, with the OPPOSITE convention from DatePicker@0.0.46 right above it — easy to confuse since both are non-"Modern"-prefixed and both look like the obvious "just use the classic one" choice. On Classic/DatePicker@2.6.0, DefaultDate is the settable property, and SelectedDate is read-only (used elsewhere, e.g. otherControl.SelectedDate, exactly like ModernDatePicker — not like DatePicker@0.0.46 just above). Setting SelectedDate directly in this control's own Properties: block throws PA2108: Unknown property 'SelectedDate', confirmed via the real Layer A parser (not guessed) 2026-07-24, Branch Contact Groups scrManageGroups datEditManualDate. This is exactly the trap the top of this file warns about — assumed SelectedDate carried over from the DatePicker@0.0.46 entry two lines up because both are "Classic-ish," shipped it without testing, and it was real, live, reported via GitHub issue. When in doubt between these two, write a tiny isolated test screen and run it through payaml-validate's Layer A directly — that's what actually resolved this, not re-reading docs or guessing a third property name.

• Attachments@2.3.0 placed directly on a screen, unbound, expecting it to work as a standalone file picker. Microsoft's own control docs state a real limitation: "The upload and delete functionality works only inside a form. The attachment control appears disabled when in Edit mode and not inside a form." A bare Attachments@2.3.0 control with no Form@2.4.4 parent — the obvious first attempt for "let the user pick a file without writing to a live SharePoint list" — renders but silently refuses add/delete clicks. Confirmed working alternative, already live-audited in this repo's own reference/external/powerappsui/file-upload.md component: set Items: =Blank() (not omitted, not a schema-less [] literal — Blank() specifically), give the control OnAddFile that does Clear(colStaging); Collect(colStaging, Last(Self.Attachments)); Reset(Self) to capture the picked file into a local collection and immediately empty the control's own internal state, and place a fully transparent click-catcher Button behind the Attachments control (declared earlier in Children, per normal z-order rules) with OnSelect: =Select(attachmentsControlName) to trigger the native picker from custom-styled "click to select / drag and drop" UI. With Items: =Blank(), the control is not bound to any real data source, so the "must be inside a form" limitation — which is about persisting SharePoint/Dataverse attachment changes via SubmitForm — does not apply; the control still fires OnAddFile and exposes Self.Attachments (Name/Value fields, Value being the file blob) normally. Read the staged file back out of the local collection (First(colStaging).Name / .Value), e.g. to pass into a Flow.Run(...) call, never from the control's own .Attachments after the fact (it gets Reset() on every add). Confirmed live: Training Tracker scrCourseDetail certificate-upload redesign, 2026-07-30 — first draft used a bare unbound Attachments@2.3.0 with no click-catcher, caught against the MS docs mirror before shipping (not live-tested broken), then rebuilt using the proven powerappsui pattern.

• A data-source action function (e.g. Office365Users.SearchUserV2(...)) written directly inside a Gallery's Items property. Unlike a pure formula, an action call sitting in a reactive property gets re-evaluated far more often than "once per keystroke" — any unrelated re-render elsewhere on the screen can re-trigger it, since Power Apps re-runs the whole dependency graph, not just the control that changed. Symptom reported live: a thin loading indicator repeatedly sweeping across the top of the screen ("like PowerApps is constantly trying to update something"), and an open lightbox that felt unstable while search boxes with this pattern were present nearby. Fix: never put a connector/action call directly in Items. Move it to the search textbox's OnChange, doing an explicit ClearCollect(colName, Office365Users.SearchUserV2(...)), and point the gallery's Items at that plain collection instead. Same live-as-you-type UX (OnChange still fires on every keystroke), but the connector is only invoked when the text actually changes, not on every unrelated re-render. Remember Reset() does not fire OnChange — anywhere the search textbox gets Reset()'d (closing a lightbox, after a successful add), also explicitly re-ClearCollect the results back to empty, or the stale results silently linger. Confirmed pattern in Branch Contact Groups scrManagePeople (galAddPersonGalResults) and scrManageGroups (galGalResults, galMaintainerGalResults), 2026-07-29 — all three had the connector call directly in Items.

Unverified — Found in Microsoft Docs, Not Yet Empirically Confirmed In This App

Per user directive 2026-07-06 ("don't just search Microsoft documents, Bible is the Bible... if it's not in the Bible, put it in there"): Microsoft Learn is no longer a default first-resort source for this app family — it has already been the direct source of confirmed-wrong claims here (ModernDatePicker.SelectedDate, ModernCombobox instability). Anything below was found via Learn/WebSearch, not by pasting it into the real editor, and must be moved out of this section into the main body (with the app/screen/date it was confirmed on) the first time it's actually verified working live — or deleted if it turns out wrong.

• Horizontal container "Horizontal Overflow" property — likely YAML name LayoutOverflowX, value LayoutOverflow.Scroll / LayoutOverflow.Hide. Per Microsoft's Horizontal container control doc page: "Horizontal Overflow - Defines whether the container shows scrollbars or remove content when it is too large to fit. Scroll and Hide." This is presented as a properties-pane UI setting (like Gap/Direction), not necessarily a formula-bar property — same insert-time/UI-only pattern already confirmed for LayoutDirection/LayoutGap on this control family. Parallels the already-confirmed LayoutOverflowY (vertical AutoLayout scroll, in the main Control Properties section above) closely enough to be plausible, but not tested live here. Before relying on this: check the properties pane for an "Overflow" setting near Gap/Direction on the Horizontal container in question.

Guide-Writing

• “Same as above.”
• “Duplicate the previous screen.”
• “Use the same technique.”
• Long inline control paragraphs that hide exact properties.
• Background/card/panel/gallery-row controls without a layer-order note when they can cover other controls.
• Formulas that may temporarily red-line without a reassurance note explaining what later control/collection/variable resolves it.
• Grouping instructions that hide layer-order requirements or fail to list exactly which controls are included/excluded.
• Long property lists that mix actual changes with default values without marking which are defaults.
• Repeating fresh-control defaults from powerapps-control-defaults.md as if the user must manually change them.
• Repeating Fill=RGBA(0,0,0,0) on normal Label controls as if it must be manually changed.
• Repeating BorderThickness=0 on normal Label controls as if it must be manually changed.
• Repeating SelectMultiple=true on modern Combo box controls as if it must be manually changed.
• Repeating ItemDisplayText=ThisItem.Value on modern Combo box simple value tables as if it must be manually changed.
• Treating a property omitted from the fresh-control export as a guaranteed literal default value.
• Control rows that say only “see formula below” when the formula can be placed in a collapsed copyable block beside the control.
• Any instruction that depends on visual guessing rather than exact control names and properties.
• Re-pasting full screen YAML to fix a single property. Targeted property changes are always safer and preserve existing customisations.

Full Modern Control Catalogue (2026-07-05)

Microsoft's index page lists 23 modern controls total. Not all are documented in depth below yet — only the ones verified/used or likely to matter for this app family. Full list for reference: Avatar, Badge, Button, Card (preview), Checkbox, Combobox, Copilot answer (preview), Data Grid (preview), Date picker, Dropdown (preview), Header, Info button, Link, Number input, Progress bar, Radio group, Spinner, Slider, Stream (preview), Table (preview), Tabs/tab list, Text, Text input, Toggle. Copilot answer, Data Grid, Table, and Stream skipped below as niche/preview and not yet needed by any app in this family — fetch their pages the same way if a future build needs them.

Baseline Warning

Microsoft's modern controls are in active change. Microsoft Learn notes that modern controls received updated versions from February 2026 with new property names, enum values, and behavior changes. Recheck Microsoft Learn before using a control not listed here or before changing a property convention.

Modern Text Input

Use for single-line, multi-line, password, and search text entry.

Verified key properties:

• Default - initial text value.
• Text - current entered text, used in formulas.
• Placeholder - hint text when empty.
• Type - use enum values such as TextInputType.SingleLine, TextInputType.Multiline, TextInputType.Password, TextInputType.Search.
• TriggerOutput - use enum values such as TriggerOutput.Keypress, TriggerOutput.FocusOut, TriggerOutput.Delayed.
• Required, ValidationState, DisplayMode, Visible.
• Layout/style: X, Y, Width, Height, Align, PaddingTop, PaddingBottom, PaddingLeft, PaddingRight, Font, Size, Color, FontWeight, Italic, Underline, Strikethrough, Fill, BorderColor, BorderStyle, BorderThickness, RadiusTopLeft, RadiusTopRight, RadiusBottomLeft, RadiusBottomRight.

Do not use:

• HintText for modern Text input. Use Placeholder.
• FontSize if the current updated modern Text input control exposes Size; older guide rows may still use FontSize and should be checked in the live editor before final publishing.

Modern Combo Box

Use for searchable selection, especially multi-select.

Verified key properties:

• Items
• ItemDisplayText - formula that determines the visible text for each item. Use ThisItem to reference the current row.
• DefaultSelectedItems
• SelectMultiple
• InputTextPlaceholder - hint text in the input field.
• AccessibleLabel, IsSearchable, Visible, DisplayMode
• Layout/style properties including X, Y, Width, Height, padding, color, font, fill, border, and radius properties as exposed by the current modern control.

Do not use:

• Placeholder for modern Combo box. Use InputTextPlaceholder.
• Missing ItemDisplayText when Items is record-shaped and the display field is not Value. Office365Users search rows in this guide use ThisItem.DisplayName.
• Default for multi-select preselection. Use DefaultSelectedItems.
• .Selected when SelectMultiple=true and the formula needs all values. Use .SelectedItems.

Known build note:

• In the user's current Power Apps editor, SelectMultiple=true is the default for modern Combo box. Set SelectMultiple=false explicitly for single-selection Combo boxes.
• In the user's current Power Apps editor, ItemDisplayText=ThisItem.Value is the default for modern Combo box simple value tables. Do not list it as a manual step unless it is a labelled default/safety check.
• ItemDisplayText must match the shape of Items. ThisItem.Value only works when Items is a simple value table or SharePoint choice-style table with a Value field.

Modern Dropdown

Use for a single fixed selection. Microsoft recommends Combo box for multi-select.

Verified key properties:

• Items
• ItemDisplayText - formula that determines the visible text for each item. For a table like {Label: "...", Months: 12}, use ThisItem.Label.
• Default
• OnChange
• ValidationState
• Required
• AccessibleLabel
• Visible, DisplayMode
• Style/layout properties including Appearance, BasePaletteColor, Font, Size, Color, FontWeight, Italic, Underline, Strikethrough, Fill, BorderColor, BorderStyle, BorderThickness, radius and padding properties.

Do not use:

• DefaultSelectedItems; that belongs to Combo box style selection, not modern Dropdown.
• Multi-select patterns; use Combo box instead.
• Old "display/value field" wording for table-shaped items. State ItemDisplayText explicitly.

Modern Toggle

Use for true/false state.

Verified key properties:

• Checked - initial/current boolean state used by this guide pattern.
• Label - caption text beside the toggle.
• OnCheck, OnUncheck, OnSelect.
• AccessibleLabel, Visible, DisplayMode.

Do not use:

• .Value to read a modern Toggle in this guide. Use .Checked.
• Text for the visible caption. Use Label.
• Default for the initial state in this guide. Use Checked.

Modern Button

Use for real clickable commands.

Common verified properties:

• Text
• OnSelect
• DisplayMode
• Visible
• BasePaletteColor
• X, Y, Width, Height
• Font and style properties exposed by the current modern Button control.

Do not use modern Button as a rounded static card unless the live editor supports all needed view/hover styling. The Training Tracker guide uses classic Button for static rounded panels.

Classic Button As Rounded Panel

Use this established Training Tracker pattern for cards and rounded panels.

Required properties:

• Text=""
• DisplayMode=DisplayMode.View
• Fill=<panel color>
• HoverFill=<same panel color>
• PressedFill=<same panel color>
• BorderColor, BorderThickness
• RadiusTopLeft, RadiusTopRight, RadiusBottomLeft, RadiusBottomRight

Do not use:

• Rectangle control for rounded panels. In this guide family, rounded panels are classic Buttons.

Classic Gallery

Use for lists of records and repeated row layouts.

Verified core properties:

• Items
• Template sizing and child controls.
• Formula context supports ThisItem.
• For nested formulas, use As aliases or capture ThisItem first with With.

Do not assume:

• A row index property exists.
• ThisItem.ID exists in a collection unless the collection explicitly contains ID.

Classic Icon

Use for action icons where Power Apps provides built-in icon shapes.

Verified core properties:

• Appearance, size, position, and OnSelect.

Do not use:

• Icons as a substitute for accessible labelled buttons unless the guide includes a clear accessible label or nearby text.

Classic Edit Form And Attachments

Use classic Edit form when SharePoint attachments are required. The Training Tracker certificate upload depends on the classic Attachments card pattern.

Verified core properties:

• DataSource
• Item
• form mode actions such as NewForm, EditForm, SubmitForm, ResetForm.

Do not replace with:

• A modern-only control pattern unless attachments have been reverified in the target tenant/editor.

Modern Progress Bar (Progress@1.1.34)

Displays determinate (Value/Max) or indeterminate (loading) progress. No native ProgressBar control name exists — the real control type is Progress.

Verified key properties:

• Value – number, 0 to Max. Only applies when Indeterminate = false.
• Max – the number that represents 100%. Not required to be 100 — set it to a real count (e.g. CountRows(...)) and skip doing percentage math yourself.
• Indeterminate – true/false. When true, Value/Max are ignored (animated loading state).
• ProgressColor – plain string literal, not a typed enum: ="Brand", ="Success", ="Error", or ="Warning". Confirmed live via a real control paste 2026-07-05 (="Square" shown in the formula bar) — do not assume this follows the same 'XCanvas.Y'.Z enum pattern as Badge below; it doesn't.
• Shape – plain string literal: ="Square" or ="Rounded".
• Thickness – plain string literal: ="Medium" or ="Large".
• BasePaletteColor – only matters if you want a colour outside the four ProgressColor presets.
• No Min property. No Fill/BorderColor — colour is controlled only via ProgressColor/BasePaletteColor.

Full property list (from the properties panel, confirmed 2026-07-05): AccessibleLabel, BasePaletteColor, ContentLanguage, DisplayMode, Height, Indeterminate, Max, OnChange, ProgressColor, Shape, Thickness, Value, Visible, Width, X, Y.

Why this entry exists: built for the Policy Tracker Main screen redesign's readiness bar and Release Pipeline widget — first went in as hand-rolled Rectangle pairs (track + coloured fill) because this control wasn't in this file yet, and its exact syntax couldn't be safely guessed for a full-screen YAML paste. Real control export from the user's own tenant is what unblocked it.

Modern Badge (Badge@0.0.24)

Already in live use in Main.yaml (Version control) — confirmed real formulas, not just docs:

Appearance: ='BadgeCanvas.Appearance'.Tint
ThemeColor: ='BadgeCanvas.ThemeColor'.Success
Shape: ='BadgeCanvas.Shape'.Rounded

Contrast this with Progress bar above: Badge uses typed 'XCanvas.Y'.Z enums, Progress bar uses plain string literals for what look like equivalent style properties (Shape, colour state). The two controls do NOT share a syntax convention — always verify per-control, never assume.

Other properties (per docs, not yet confirmed live): Content, ThemeColor (docs list brand/danger/important/informative/severe/subtle/success/warning — note the real app uses .Success capitalised as a typed enum member, and Tint appears as a real Appearance value that isn't in the docs' filled/outline/ghost/inverted list, so the docs are incomplete here — trust the live export over the prose), BasePaletteColor, standard Font* properties, AccessibleLabel, DisplayMode.

Modern Avatar (ModernAvatar, exact version unconfirmed)

Not yet used in any app in this family — worth using instead of hand-rolled initials-circle Labels (the pattern currently used for owner avatars on Policy Tracker's Main screen cards).

Verified key properties (per docs, not live-confirmed):

• Name – drives the initials shown when there's no image.
• Image – photo, e.g. ThisItem.Owner.Picture or Office365Users.UserPhotoV2(...).
• Badge – small status decoration.
• Shape – Circular or Square.
• Appearance – Brand (theme colour), Neutral (grayscale), or Colorful (hash-of-Name colour — useful for auto-varied owner colours without hand-picking a palette).
• BasePaletteColor, standard Font* properties, Out of office (adjusts the badge icon).

Get a live export before using in a full-screen paste — exact enum syntax (typed vs. string literal) unconfirmed, same caveat as everything below not yet used live in this app family.

Modern Checkbox (CheckBox@0.0.30 — note the type name has no "Modern" prefix, unlike Button/Dropdown/TextInput)

Same trap as Modern Toggle above:

• Read/set state via Checked, not .Value and not Default.
• Label is the caption text (not Text).
• OnCheck / OnUncheck / OnSelect.

Confirmed live 2026-07-24 (Branch Contact Groups recCheckBox, real Studio export via GitHub issue) — Layer A (Microsoft's real parser) accepted the control cleanly, and it renders/behaves correctly in Studio (first live confirmation of this control in this app family): - BasePaletteColor — sets the checkbox's accent colour, e.g. =RGBA(156, 220, 79, 1) for green. Same property name/pattern as ModernButton's colour property. - CheckboxSize — controls the size of the checkbox glyph itself, independent of the control's own Width/Height (which set the overall hit-target/bounding box). Confirmed live at =22 with Width/Height at =38. - Standard X/Y/Width/Height all behave as expected.

Standing default for this app family, per explicit user instruction 2026-07-24: every CheckBox@0.0.30 in Branch Contact Groups should use BasePaletteColor: =RGBA(156, 220, 79, 1) and CheckboxSize: =22 — this is the confirmed, user-approved house style, not just a one-off. Apply it by default to any new Modern Checkbox in this app, not only when asked. Width/Height stay context-dependent (a standalone tick-square like recCheckBox used =38/=38; a checkbox whose own Label also carries a long line of text inline, like chkGroupMember/chkAddPersonGroup, keeps a shorter Height — e.g. =32 — sized to the surrounding row/template instead).

Modern Date Picker

• Format – Short / LongAbbreviated / YearMonth / Custom (custom takes a format string like "dd/mm/yyyy"). Exact literal syntax (typed enum vs string) unconfirmed — verify live before use.
• SelectedDate – the output property (local time).
• StartDate / EndDate – bounds.
• StartOfWeek, IsEditable, Required.
• ValidationState – Error / None, red border on Error.
• PlaceHolder, OnChange.

Modern Number Input (ModernNumberInput@1.0.0)

• Default (input, initial value) vs. Value (output, read-only) — same input/output split pattern as Modern Slider below. Don't try to set Value directly.
• Min / Max / Step (default step is 1).
• Precision – typed enum DecimalPrecision.Auto / DecimalPrecision.'0' / '1' / '2' / '3' (note the quoted numeral syntax).
• Appearance – typed enum Appearance.Filled / Appearance.FilledDarker (default) / Appearance.Outline.
• ValidationState – ValidationState.None / ValidationState.Error.
• OnChange fires on blur/step-click, not every keystroke.
• Recent rename history (already-migrated apps may have old names): FontColor→Color, FontSize→Size, FontItalic→Italic, FontStrikethrough→Strikethrough, FontUnderline→Underline, BorderRadius→ four separate RadiusTopLeft/Right/BottomLeft/Right. TriggerOutput removed entirely.

Modern Radio Group (ModernRadio@1.0.0)

• Items, ItemDisplayText (formula using ThisItem), Default, Selected (output), OnChange.
• Layout – typed enum Layout.Vertical (default) / Layout.Horizontal.
• Best for 2-7 mutually exclusive options; use Combo Box beyond that.
• Same Font* property renames as Number Input above apply here too — this whole modern-control generation was refactored together, expect the same rename list on any control touched in the same wave.

Modern Slider (ModernSlider@1.0.0)

• Default (input, initial value) vs. Value (output, read-only) — this was a breaking rename: the old version took Value as the input property; the new version reserves Value for output only and uses Default for the initial value. If copying an old example from a blog, this will silently misbehave rather than error.
• Min (default 0) / Max (default 100).
• LayoutDirection – typed enum LayoutDirection.Horizontal (default) / LayoutDirection.Vertical. Previously a plain string "Horizontal"/"Vertical" — another breaking enum-format change.
• Size – typed enum SliderSize.Small / SliderSize.Medium (default) / SliderSize.Large. Previously a plain string.
• OnChange, Tooltip, AccessibleLabel.

This control is the single clearest illustration of the Baseline Warning at the top of this file — same control name, completely different formula syntax (string → typed enum, input/output property swap) between versions. Never trust an old example without checking the current docs' "Recent updates" section first.

Modern Spinner

For loading states (page/table loading), distinct from Progress Bar's indeterminate mode — Spinner has no track/value concept at all, it's a pure animated icon + optional label.

• Label, LabelPosition, SpinnerSize.
• Appearance – Primary or Inverted.
• AccessibleLabel, DisplayMode, OnChange.

Modern Tab List (ModernTabList@1.0.0)

Directly relevant to this app family — this is the real control for what Policy Tracker's Main_1 redesign hand-built as a GroupContainer + Classic/Button row (the segmented dashboard tab strip). Worth revisiting as a real upgrade once its exact live syntax is confirmed.

• Items, Default, Selected (output — drive content visibility off this, e.g. ContentSection.Visible = TabList1.Selected.Value = "Overview").
• OnChange (fires on tab switch) vs. OnSelect (fires on any tab click, including re-clicking the active one).
• Appearance – typed enum TabListAppearance.Transparent / .Subtle / .Underline / .Filled.
• Alignment – typed enum TabListAlignment.Start / .Center (default) / .End — this is the whole tab list's position, distinct from Align (individual tab text alignment).
• 2-7 tabs recommended; no auto horizontal scroll if too many tabs are added.

Modern Header

A prebuilt app-header control (logo + title + user photo). Deliberately NOT used as a replacement for this app family's fully custom top bars — it explicitly does not support colour customisation or app navigation, and doesn't auto-replicate across screens (must be added per screen manually). Documented here so it isn't reached for by mistake when a "modern header" is wanted; the custom conTopBar/conHeader pattern already used across Main/ViewItem/Main_1/ViewItem_1 remains the right approach for this app family.

• Title, IsTitleVisible, Logo, IsLogoVisible, LogoMaxHeight, LogoToolTip, OnSelectLogo, IsProfilePictureVisible, Style, TitleFontSize.

Modern Link (ModernLink@1.0.0)

• Text, Url (blocks unsafe schemes like javascript:), Wrap (default true).
• Type – typed enum LinkAppearance.Default / LinkAppearance.Subtle. Renamed from Appearance in an earlier version.
• Standard Font/Border/Radius* properties.

Modern Info Button (ModernInformationButton@1.0.0)

Inline "?" help icon that opens a flyout on click/hover — good candidate for field-level hint text instead of a separate hidden lblHint Label pattern already used elsewhere in this app family (e.g. lblHighPriorityHint in ViewItem.yaml).

• Content (flyout text), IconColor, OnSelect.
• Default size 32x32 — docs explicitly recommend not going smaller for tap targets.

Modern Text (ModernText@1.0.0)

Already in live use throughout Main.yaml (the Published/ReadyForRelease/ApprovedBy/LinkCount pill labels on release cards) — confirmed real control, not just docs.

• Text, Size, Color, FontWeight, Align, VerticalAlign (default is now Middle), Wrap, AutoHeight.
• Fill, BorderColor, BorderThickness, RadiusTopLeft/Right/BottomLeft/Right — this control CAN look like a pill/badge on its own (fill + border + radius), which is exactly how the real app already uses it for the release-card pills.
• DisplayMode was removed from the properties panel in a recent update — the property still technically exists for backward compatibility but has no visible effect. Don't rely on it to lock down a ModernText control; use Visible instead if it needs to disappear.
• OnSelect now exists (didn't used to) — a ModernText can be a clickable label directly now, no need to layer an invisible Button on top purely for click behaviour (though the full-card-click pattern documented in known-bad-patterns.md/live-build-lessons may still prefer a Rectangle/Button for other reasons — this doesn't override that, just noting the option exists).

Modern Card (ModernCard@1.0.0, preview)

Preview control — treat with extra suspicion in a full-screen YAML paste. The prose docs and the code examples on the same page don't even agree with each other: prose says the image-position property is ImagePosition, but every YAML example on the page uses ImagePlacement instead. That kind of doc/example mismatch is exactly the sort of thing that has broken pastes in this app before — get a live export before trusting either name.

• Title, Subtitle, Description, Image, ImageAltText, HeaderImage, HeaderImageAltText.
• Direction (prose) / LayoutDirection (example) — same naming inconsistency as above, LayoutDirection.Horizontal is what the actual YAML examples use.
• Fill auto-contrasts title/subtitle/description text colour unless TitleColor/SubtitleColor/DescriptionColor are set explicitly.
• Could be a real upgrade path for Policy Tracker's hand-built release-list item cards eventually, but not until this control's real property names are confirmed live — don't use it in a full-paste screen override until then.

Label (Label@2.5.1) — Tooltip property

Confirmed live 2026-07-24 (Branch Contact Groups, lblRowTitle/lblGroupName) via an isolated payaml-validate Layer A test before use — Tooltip is a valid property on Label@2.5.1, showing the given text on hover. Useful pattern: combine with a character-cap truncation formula on Text (e.g. =If(Len(full) > N, Left(full, N) & "...", full)) so long dynamic text gets a visible "..." cutoff plus a full-text tooltip on hover, rather than silently clipping via Wrap: =false alone with no way to see the rest.

Control Defaults (Fresh-Control Lab)

Power Apps Control Defaults

Last checked: 2026-06-20

This reference is generated from fresh controls inserted into the live Power Apps editor without manual edits.

Source Evidence

• Classic fresh-control lab: .sources/default-lab/LabClassic.txt (18 parsed controls)
• Modern fresh-control lab: .sources/default-lab/LabModern.txt (49 parsed controls)

Interpretation Rules

• Treat these as observed defaults from the user's tenant/editor, not universal Microsoft documentation.
• A serialized property means the fresh control export explicitly contained that property.
• An omitted property means the fresh control did not serialize it; do not invent a literal default value from absence alone.
• X and Y came from the repeated insert positions in the lab. Do not use them as default evidence.
• Width, Height, theme colors, font values, generated gallery children, and generated template formulas can be useful evidence, but still check whether the guide is intentionally changing behavior.
• Future guide rows should use this file to remove or label default-only properties as leave default or default/safety check.

External Research: ChatGPT Property Matrix (context + precedence rule)

External Research: ChatGPT Control Property Matrix (2026-07-05)

Three files landed in reference/external/ from a separate ChatGPT research pass: powerapps_canvas_control_bible_v0_1.md (curated summary, ~870 lines), powerapps_canvas_control_property_matrix_v0_1.csv (raw property matrix, 412 rows), and powerapps_canvas_control_bible_schema_v0_1.json (the CSV's column schema).

What this is good for

Much broader property-name coverage than this Bible had compiled by hand — 412 property rows across every Modern and Classic control Microsoft documents, including controls this project hasn't touched yet (e.g. it flagged a Rating modern control that was missing from CONTROL_VERIFICATION_CHECKLIST.md in the Policy Tracker repo — added there now). Use it as a property-name dictionary: if you're not sure whether a property exists on a control, check here first before guessing.

What this is NOT

It is honest about its own limits (its own intro says exactly this): it's derived from Microsoft's documentation pages, the same source class that has been wrong or incomplete multiple times in this project's actual live builds — ModernDatePicker. SelectedDate not being settable, ModernCombobox.Reset() clearing the selection instead of restoring it, Required not suppressing the clear-X on ModernDropdown, GroupContainer.DropShadow defaulting on. None of those specific facts would have been caught by more thorough documentation scraping, because the documentation itself doesn't mention them — they were only found by touching the real, running control.

Its own confidence levels reflect this: of the 412 rows, ~171 are "High" (from an individual control's docs page), ~180 are "Medium" (inferred/shared, not verified per control), and the rest are "Gap flagged" (property list not even fully harvested yet). None are independently runtime-verified.

Precedence rule

When this external research conflicts with known-bad-patterns.md or live-build-lessons.md, this project's own empirically-confirmed entries win, every time. This matrix is a starting point for coverage on controls we haven't verified yet, not a correction to anything we've already confirmed the hard way.

Two genuinely useful pointers surfaced by this research (not yet followed up)

• microsoft/power-platform-skills issue 101 — hidden/generated properties (e.g. SearchItems on searchable controls) that don't show up via describe_control/standard tooling. Worth checking if a control ever seems to have an internal property we can't find documented anywhere.
• microsoft/power-platform-skills issue 146 — PowerBIIntegration, a runtime-injected host object, not a normal insertable control — can surprise an offline schema/compiler if ever encountered.

ChatGPT Control Property Matrix (2026-07-05, docs-derived, unverified)

Power Apps Canvas Control Bible v0.1

A local, source-backed reference for Power Apps canvas controls, classic and modern. Built from the research session on 5 July 2026. This is deliberately honest: it separates confirmed Microsoft documentation from inferred/common properties and known gaps. It is useful now, but it is not pretending Microsoft has published a perfect canonical metadata dump.

Known gaps and traps

Recommended harvesting workflow

Use this workflow to turn v0.1 into a genuinely brutal local knowledge base. | Step | Action | Output | | --- | --- | --- | | 1 | Clone or download MicrosoftDocs/powerapps-docs controls folder and modern-controls subfolder. | Local markdown source cache. | | 2 | Parse every markdown page for Properties, Key properties, Additional properties and Applies to tables. | Raw property rows. | | 3 | Merge shared property pages into every control where the page says the property applies. | Normalised property matrix. | | 4 | Insert every control into a blank canvas app, open Code view, copy YAML, then export .msapp/.pa.yaml. | Studio-observed property baseline. | | 5 | Compare docs properties vs Studio properties vs .pa.yaml. | Gap report: missing, renamed, hidden, generated, runtime-only. | | 6 | Add community/tooling issues as annotations only, not as official truth. | Confidence notes. | | 7 | Regenerate Markdown, CSV and optional DOCX monthly or before major builds. | Versioned local Bible. |

Copy/paste prompt for Claude or Codex to continue the extraction

Use this as a build prompt if you want an agent to complete the harvester against a local clone:

Build a Power Apps canvas control documentation harvester. Use the local MicrosoftDocs/powerapps-docs repository. Parse powerapps-docs/maker/canvas-apps/controls and controls/modern-controls. For every markdown file that represents a control, extract control name, classic/modern family, page path, description, key properties, additional properties, enum/value notes, deprecation/preview notes, and source line references where possible. Then parse shared property pages properties-core, properties-text, properties-accessibility, properties-size-location, and properties-color-border, and join shared properties to controls where the docs say they apply. Emit powerapps_controls.json, powerapps_properties.csv, gap_report.md, and bible.md. Mark each property confidence as direct, shared-inferred, community, runtime-only, or needs-studio-verification. Do not invent missing enum values.

Version notes

v0.1 is a grounded starter Bible, not a final canonical dump. It prioritises truthfulness over fake completeness. The next version should automate extraction from the docs repository and then validate by Studio Code View.

Live Build Lessons

Live Build Lessons

Last checked: 2026-06-23

These are lessons learned from the Training Tracker live build — real bugs hit and diagnosed in the Power Apps editor and via GitHub issue threads. They supplement real-build-quirks.md. Do not overrule them based on what seems logical; they are ground truth.

Character Escapes Don't Work in Power Apps Strings

Power Apps formula strings do not support \x or \u escape sequences. Writing \xB7 outputs the literal characters \, x, B, 7 — not the middle dot ·.

Use Char(decimal) instead:

Char(183)

This produces · (U+00B7, middle dot / interpunct). This is the correct approach for any Unicode character by decimal code point.

Common ones used in Training Tracker:

Never write \xB7, ·, or any escape sequence in a Power Apps string literal.

Version Stamps Are Mandatory on Every Screen Page and Index

Every pa-yaml-wrap call and every docs/index.html must carry a version label and a build timestamp. Without them, the user cannot tell whether GitHub Pages has served the latest push — F5 refreshes look identical.

For screen pages, always pass --version:

pa-yaml-wrap scrHome.yaml docs/screens/scrHome.html --version v1.2

The stamp appears bottom-right in small monospace text: v1.2 — Built 23 Jun 2026 10:55 BST

For docs/index.html, add the version inline after the <h1> title and a build timestamp line below it. Use date '+%-d %b %Y %H:%M %Z' to get the local time string.

Version convention: start at v1.0, bump minor for each fix/push (v1.1, v1.2), bump major for structural changes. Every push that modifies screen content increments the version so the stamp visibly changes.

PA1006/PA1001 — Screen YAML Uses Screens: Root, Not Screen-Level Control

Error: (1,3) : error PA1006 : Empty or invalid value for Control.

Screen paste YAML must use the Source Code schema root:

Screens:
  scrDashboard:

Do not paste a bare top-level list item such as - scrDashboard:. If the paste starts with - scrDashboard:, Power Apps reports the error at line 1, column 3 even when Control: Screen is present, because the screen is not under the Screens: schema root.

Once the screen is under Screens:, do not add Control: Screen. SchemaV3 screen instances do not expose a Control property. Adding it causes:

(3,5) : error PA1001 : YamlInvalidSyntax: Property 'Control' not found on type 'Microsoft.PowerPlatform.PowerApps.Persistence.PaYaml.Models.SchemaV3.ScreenInstance'.

Wrong:

- scrDashboard:
    Control: Screen
    Properties:
      Fill: =RGBA(248,248,248,1)

Correct:

Screens:
  scrDashboard:
    Properties:
      Fill: =RGBA(248,248,248,1)

Child controls under Children: still need normal Control: values such as Label@2.5.1 or Classic/Button@2.2.0. The no-Control rule applies only to the screen node under Screens:.

When checking with a standard YAML parser such as yaml.safe_load, quote any single-line Power Fx formulas that contain YAML-significant : text, for example record literals or labels with colons:

Default: '={Value: "New to MoD/Branch"}'
Text: '=If(IsBlank(varRole), "Role not set", "Role: " & varRole)'

The quotes are YAML syntax only; the parsed Power Fx value still starts with =.

Copy Pages Must Show and Guard the Actual Clipboard Payload

A repeated paste error can be caused by stale browser page content or stale clipboard text even after the repository has the corrected YAML. Version stamps alone are not enough proof that the copied payload is the corrected payload.

Every generated screen copy page should visibly show the first lines of the exact YAML string that the Copy button will write. For screen YAML, the preview must start:

Screens:
  scrName:
    Properties:

The copy script should refuse to copy known-invalid screen payloads, especially:

Screens:
  scrName:
    Control: Screen

If Power Apps reports (3,5) Property 'Control' not found on type ... ScreenInstance, the pasted clipboard text still contains a screen-level Control: Screen. Check the visible payload preview on the live copy page before changing YAML again.

Use versioned or cache-busted links from index pages, for example screens/scrDashboard.html?v=1.9, so the browser does not reuse an older generated screen page.

PA2109 — Gallery Variant Names Are Case-Sensitive

Error: (255,9) : error PA2109 : Unknown variant 'verticalGallery' for control type 'Gallery@2.15.0'.

For classic Gallery@2.15.0, use the verified variant names from the exported working screens and fresh-control defaults:

Control: Gallery@2.15.0
Variant: Vertical

Do not use generated/web-style names such as:

Variant: verticalGallery

Known valid classic gallery variants include:

• Vertical
• Horizontal
• VariableHeight

The variant value is case-sensitive and schema-checked before Power Fx formulas are evaluated, so a wrong variant blocks the entire screen paste.

PA2108 — Labels Do Not Support Radius Properties

Error:

error PA2108 : Unknown property 'RadiusTopLeft' for control type 'Label@2.5.1'.
error PA2108 : Unknown property 'RadiusTopRight' for control type 'Label@2.5.1'.
error PA2108 : Unknown property 'RadiusBottomLeft' for control type 'Label@2.5.1'.
error PA2108 : Unknown property 'RadiusBottomRight' for control type 'Label@2.5.1'.

Label@2.5.1 can use Fill, Color, Align, VerticalAlign, and text styling, but it does not expose radius properties in the PaYaml schema. Do not use Label controls for rounded pills/badges.

For rounded badges or status pills, use the established Classic Button pattern with DisplayMode=DisplayMode.View:

- btnStatusPill:
    Control: Classic/Button@2.2.0
    Properties:
      Text: ="Active"
      DisplayMode: =DisplayMode.View
      Fill: =RGBA(220,238,234,1)
      HoverFill: =Self.Fill
      PressedFill: =Self.Fill
      Color: =RGBA(0,78,66,1)
      BorderThickness: =0
      RadiusTopLeft: =12
      RadiusTopRight: =12
      RadiusBottomLeft: =12
      RadiusBottomRight: =12

If a label already exists and the rounded shape is not critical, remove the four radius properties rather than blocking the whole paste.

PA1001 — |- Block Scalars Are Only Safe on Event Handlers and Items

PaYaml (PowerApps' YAML dialect) does not reliably support |- block scalars on visual or style properties. Using |- on Fill, Color, Visible, Text, DisabledFill, HoverFill, or any similar property causes PA1001 YamlInvalidSyntax even when the YAML is structurally valid and passes a standard YAML parser.

Properties where |- is safe: - OnSelect, OnChange, OnVisible, OnCheck, OnUncheck — event handlers - Items — gallery/dropdown data source

Properties where |- must NOT be used — use a single-line formula instead: - Fill, HoverFill, PressedFill, DisabledFill - Color, HoverColor, PressedColor - Visible - Text - BorderColor, BasePaletteColor - Any other visual/style property

Wrong:

Fill: |-
  =If(
      ThisItem.Complete,
      RGBA(34,139,34,1),
      RGBA(163,100,0,1)
  )
Visible: |-
  =varSelectedRecord.'Movement Type'.Value = "Leaving Branch" ||
  varSelectedRecord.'Movement Type'.Value = "Leaving MoD"

Correct:

Fill: =If(ThisItem.Complete, RGBA(34,139,34,1), RGBA(163,100,0,1))
Visible: =varSelectedRecord.'Movement Type'.Value = "Leaving Branch" || varSelectedRecord.'Movement Type'.Value = "Leaving MoD"

Even a long single-line formula is safe. Multi-line with |- on style properties is not.

PA1001 — Three Rules for |- Block Scalars (All Must Hold)

All three errors share the code PA1001 YamlInvalidSyntax. They are distinct causes and must be checked independently.

Rule 1 — Any multi-line formula must use |-, never inline

Error message: While parsing a block mapping, did not find expected key.

YAML cannot span an unquoted scalar value across multiple lines in a block mapping. If a formula opens a parenthesis on the key line without closing it, the next line is parsed as a new key — which fails.

Wrong:

Fill: =If(
    ThisItem.Complete,
    RGBA(34,139,34,1),
    RGBA(163,100,0,1)
)

Correct:

Fill: |-
  =If(
      ThisItem.Complete,
      RGBA(34,139,34,1),
      RGBA(163,100,0,1)
  )

Pre-output scan: For every Key: = line, count ( and ) on that line. If open count > closed count, the formula continues onto the next line — it must use |-. Applies to every property: Fill, Color, DisabledFill, HoverFill, Text, Visible, OnSelect, and all others.

Rule 2 — Every |- block's first content line must start with =

Error message: Power Fx expressions must start with '='

The = prefix marks the value as a Power Fx formula. It is required on the first content line only — continuation lines do not get it. This applies to every property that uses |- without exception: event handlers (OnSelect, OnChange, OnVisible, OnCheck, OnUncheck) and data properties (Items, Fill, Color, Visible, Text, etc.).

Wrong:

OnSelect: |-
  Patch('MyList', varRecord, {Field: Today()});
  Navigate(scrRecord)

Correct:

OnSelect: |-
  =Patch('MyList', varRecord, {Field: Today()});
  Navigate(scrRecord)

Pre-output scan: For every |- in the YAML, check that the immediately following non-empty line starts with =.

Rule 3 — Inside a |- block, indentation must follow paren depth

Error message: While parsing a block mapping, did not find expected key. (same as Rule 1, different cause)

When a |- block contains a nested formula like If(condition, If(...)), each line's indentation must match its logical paren depth. A common mistake when converting inline formulas to |- is to carry over original whitespace mechanically — this places the outer closing ) at the wrong indent level, making the YAML parser see it as a key instead of formula continuation.
