The +client falls back to layout table rendering, and the tabular relationships +between fields are lost — screen readers cannot associate a "header" field +with its corresponding "value" field. + +There are two ways this manifests: + +1. **Hidden captions on editable fields in a non-data-table grid.** + The field has `ShowCaption = false` but there are no `` headers to + compensate. The field has no accessible label at all. + +2. **Fields used as labels for other fields.** + One field (e.g., "Statement Period") is intended to serve as a row header + for another field (e.g., "Statement Balance"), but since it renders as a + layout table, there is no programmatic association between them. A screen + reader will announce each field independently with no relationship. + +Flag a grid as an accessibility issue when ANY of these are true: +- An editable field has `ShowCaption = false` and the grid does NOT meet + ALL data table conditions +- Fields are arranged so that one field is clearly intended to label or + describe another field (tabular data intent), but the grid does NOT meet + ALL data table conditions +- A grid is **nested inside another grid**.

If yes, `ShowCaption = false` is correct. If no, ask: is + the developer arranging fields with tabular intent (one field labels + another)? If so, the grid must be fixed to meet data table conditions. + Otherwise, ensure editable fields keep their captions and only standalone + content fields hide theirs. + +## STYLE PROPERTY — COSMETIC VS SEMANTIC STYLES + +The `Style` property on page fields controls text formatting. Some style +values are purely cosmetic (visual formatting only), while others carry +semantic meaning that is conveyed through color. For accessibility, assume +that the style is completely invisible to the user — the meaning must be +fully determinable from the field caption, value, or adjacent fields. + +COSMETIC STYLES (always safe — DO NOT flag these): +These styles change visual appearance but do not convey semantic meaning. +They NEVER require additional context and must NOT be reported as findings: +- None, Standard +- StandardAccent (Blue) +- Strong (Bold), StrongAccent (Blue + Bold) +- Attention (Red + Italic), AttentionAccent (Blue + Italic) +- Subordinate (Grey) + +This applies whether the cosmetic style is set via `Style` or via a +`StyleExpr` Text variable. If the resolved style is cosmetic, it is safe. + +SEMANTIC STYLES (require additional context — flag ONLY these three): +Only the following three styles carry semantic meaning through color: +- **Favorable** (Bold + Green) — implies a positive outcome +- **Unfavorable** (Bold + Italic + Red) — implies a negative outcome +- **Ambiguous** (Yellow) — implies an uncertain or mixed outcome + +EXCEPTION — CUE TILES (fields inside a `cuegroup`): +Fields inside a `cuegroup` render as cue tiles. The client automatically +provides an accessible label for semantic +styles on cue tiles (e.g., "Favorable", "Unfavorable"), so semantic styles +in a `cuegroup` do NOT need additional context and can be ignored for this +analysis. + +RULE: When a semantic style (Favorable, Unfavorable, Ambiguous) is used, +the semantic meaning MUST be independently determinable without seeing the +color. At least one of these conditions must be true: +1. The **field caption** matches the semantic meaning (e.g., caption is + "Error" with Style = Unfavorable, or "Profit" with Style = Favorable) +2. The **field value** communicates the meaning (e.g., value is "Success!" + with Favorable, or a negative number with Unfavorable, or "Something + went wrong" with Unfavorable) +3. An **adjacent field** provides a textual representation of the semantic + meaning (e.g., a separate "Status" column reads "High" / "Medium" / + "Low" alongside a percentage field styled with Favorable / Ambiguous / + Unfavorable) + +This rule applies equally whether `Style` is set to a literal value or to +a variable that evaluates to a semantic style at runtime. + +NOTE ON `StyleExpr`: In AL, `StyleExpr` serves two distinct purposes +depending on its type: +- **Boolean**: When `StyleExpr` is a Boolean (or Boolean expression), it + controls whether the `Style` property is applied. In this case, analyze + the `Style` property value — `StyleExpr` itself can be ignored. +- **Text**: When `StyleExpr` is a Text variable (e.g., `StyleExpr = StatusStyle` + where `StatusStyle` is declared as `Text`), the variable contains the style + name at runtime (e.g., `StatusStyle := 'Favorable'`). In this case, there + may be no `Style` property at all — the `StyleExpr` variable IS the style. + Trace the variable assignments in OnAfterGetRecord or OnAfterGetCurrRecord + to determine which semantic styles may be applied, then apply the same + rules as for a literal `Style` value. + +Good — field value communicates the semantic meaning: +```al +field(ProfitMargin; Rec."Profit Margin") +{ + // Positive values show as green, negative as red. + // The sign of the number (+/-) independently conveys the meaning. + Style = Favorable; + StyleExpr = IsProfitable; // Boolean — toggles whether Style is applied +} +field(OverdueAmount; Rec."Overdue Amount") +{ + // Caption "Overdue Amount" already implies unfavorable. + Style = Unfavorable; +} +``` + +Good — StyleExpr as Text variable with values that match field meaning: +```al +field(Status; Rec.Status) +{ + // Status is an Option: Open, In Progress, Completed, Overdue. + // The option text values themselves communicate the meaning. + StyleExpr = StatusStyle; // Text — contains 'Favorable', 'Unfavorable', etc. +} +// In OnAfterGetRecord: +// case Rec.Status of +// Rec.Status::Open: StatusStyle := 'Standard'; +// Rec.Status::Completed: StatusStyle := 'Favorable'; +// Rec.Status::Overdue: StatusStyle := 'Unfavorable'; +// end; +``` + +Good — adjacent field provides semantic context: +```al +// In a grid/repeater with columns: +field(Confidence; Rec."Confidence %") +{ + StyleExpr = ConfidenceStyle; // Text — 'Favorable'/'Ambiguous'/'Unfavorable' +} +field(ConfidenceLevel; Rec."Confidence Level") +{ + // This adjacent column shows "High", "Medium", or "Low" — + // providing the textual meaning that the color alone cannot. +} +``` + +Bad — semantic style with no independent way to determine meaning: +```al +field(Confidence; Rec."Confidence %") +{ + // StyleExpr is 'Favorable' above 90%, 'Ambiguous' 70-90%, 'Unfavorable' below 70%. + // But the caption ("Confidence") and value ("85%") do not tell the user + // whether 85% is good or bad. Only the color communicates the threshold. + StyleExpr = ConfidenceStyle; // Text variable +} +``` + +Bad — semantic style used for purely cosmetic purposes: +```al +field(CompanyName; Rec."Company Name") +{ + Style = Favorable; // Green text for aesthetics — misleading, implies + // the company name is a positive value +} +``` + +COMMON ACCEPTABLE PATTERNS — DO NOT flag these: +- A **balance or amount** field styled Favorable for positive values and + Unfavorable for negative values. The sign (+/-) of the number conveys + the meaning independently. +- A field whose **caption already implies the semantic meaning**: "Overdue + Amount" with Unfavorable, "Profit" with Favorable, "Error Count" with + Unfavorable. The caption tells the user what the value means. +- An **Option or Enum** field where the option text values communicate the + state (e.g., "Open", "Completed", "Overdue") and the style matches + the text (e.g., Favorable for "Completed", Unfavorable for "Overdue"). +- A `StyleExpr` Text variable that resolves to a **cosmetic style** (e.g., + 'Attention', 'Strong'). Cosmetic styles are always safe regardless of + context. + +## JAVASCRIPT CONTROL ADD-INS + +When a developer builds a JavaScript control add-in, they bypass the +Business Central framework's built-in accessibility support and take full +responsibility for the accessibility of the rendered HTML, JavaScript, and +CSS. Review changes to control add-in implementation files for WCAG 2.1 AA +compliance and general accessibility best practices. + +NOTE TO REVIEWER: Automated review of control add-in code is inherently +non-exhaustive. Many accessibility issues (keyboard flow, screen reader +announcements, dynamic behavior) require manual testing. + +WHEN TO FLAG FOR MANUAL REVIEW: +If a control add-in diff contains changes that affect UI rendering, ALWAYS +include a finding recommending a manual accessibility review. UI changes +include modifications to: +- HTML templates or DOM manipulation (createElement, innerHTML, appendChild, + JSX/TSX markup, template literals producing HTML) +- CSS or SCSS files (any change to styling, layout, colors, visibility) +- Event handlers for user interaction (click, keydown, focus, blur) +- ARIA attributes or roles +- Dynamic visibility or content updates + +If no specific accessibility issues are found but UI-rendering changes exist, +output a single finding with severity "Low" recommending a manual review. +Do NOT output an empty array when UI-rendering changes are present — the empty array rule applies only when there are no issues and no UI-rendering changes. + +Do NOT flag for manual review if the only changes are to pure business +logic, data processing, API calls, or other non-rendering code that does +not touch the DOM or styling. + +When reporting issues in control add-in code, include a note that a manual accessibility +review is recommended for any control add-in that renders a UI. + +KEY AREAS TO CHECK: + +1. **ARIA and semantic HTML** + - Interactive elements must have accessible names (aria-label, + aria-labelledby, or visible text content) + - Use semantic HTML elements where possible (`
