…integration - Introduced `error_registry.py` to collect structured errors during AST transformation - Errors include type, filename, line number, message, and optionally component ID or atom name - Thread-safe via lock; supports register/get/clear - Updated `transform_source` to catch and register `SyntaxError` as transform errors - Enhanced error handling in `register_display_dependency_resolver` with error registration - `ScriptRunner` now: - Clears previous errors at script start - Sends either "components" or "errors:result" message based on presence of errors - Frontend: - Added `ErrorsReport.jsx` component for displaying transform errors - Updated `Dashboard.jsx` to render error fragments and align empty state formatting - `App.jsx` now handles new `errors:result` message type and routes errors to dashboard
…ovements - Add `_safe_register_error` method to AST transformer to capture structured transformation errors - Wrap most lifting and analysis methods with try/except to register errors instead of crashing - Extend error object metadata to include component ID, atom name, and extra context - Improve debug logging and error traceability throughout the AST transformer - Add `has_errors()` to BasePreswaldService for script fallback error checks - Update ErrorsReport frontend to support collapsible/expandable error lists with CSS transitions - Style error list in `components.css` and refactor JSX to allow toggling long error output - Improve resilience and recovery logic in `ScriptRunner.compile_and_run()` when runtime errors occur
- Moved `register_error` import closer to usage in `reactive_runtime.py` - Removed unused imports from `registry.py` and reordered for clarity - Replaced bare `except` with `except Exception as e` for better debugging - Added `# noqa` directives for intentional style suppressions - No functional changes
…nd error display - Add `rebuild_component_from_source()` to reconstruct components from lifted AST source - New helper functions (`get_call_func_name`, `extract_call_args`, `build_component_from_args`) in `transformer_utils.py` - Update `Workflow.execute()` to fallback to reconstructed component with `error` and `shouldRender` if runtime failure occurs - Annotate error state in `MarkdownRendererWidget` via tooltip and border styling - Modify `App.jsx` to preserve error display on component refresh and wrap in `TooltipProvider` - Add `render_tracking_suppressed()` context to `BasePreswaldService` and guard `@with_render_tracking` accordingly - Improve `AutoAtomTransformer._build_callsite_metadata()` to include parsed source and cleanup return format
…or handling - Refactored `build_component_from_args` and `rebuild_component_from_source` to consistently return `ComponentReturn` objects - Introduced `ComponentReturn.component` property for consistent access to internal component metadata - Centralized producer registration logic into `_register_component_producer` in `Workflow`, now used for both normal and fallback paths - Improved frontend error styling for Button and BigNumber widgets using `Tooltip` and `AlertTriangle` - Enforced default `size` handling on `ButtonWidget` to resolve layout conflicts - Fixed incorrect handling of reactivity flag in `ScriptRunner` - Skipped atom execution when dependencies fail instead of halting entire DAG - Added detailed docstrings for utility functions and transformer logic
- Display red border, background, and top right AlertTriangle when `error` is present - Show error tooltip on hover - Dim main alert icon to visually deemphasize original alert level in error state - Preserve layout and semantics for all alert variants
- Updated ChatWidget.jsx to display backend errors using a tooltip with alert icon and destructive styling. - Separated backend error (`error` prop) from local chat errors in the UI. - Added support for always rendering error state when present, with improved UI feedback. - Patched build_component_from_args to always include an 'id' on fallback components to prevent key errors when trying to register a producer during rebuild. - Cleaned up Atom `wrapped_func` error handling and removed redundant source fallback logic.
- Displays error icon with tooltip in top right when error is present - Adds red border and light red background for error state
- Adds error prop support to GenericWidget - Displays alert icon with tooltip in top right when error is present - Renders red border and light red background for error state - Uses consistent error UI styling with other widgets
…eWidget - Adds error prop to ImageWidget for error state support - Shows alert icon with tooltip and red border/background when error is present - Preserves original image styling and layout when not in error - Displays "Image unavailable" fallback when an error occurs
…fails - Passes safe serializable kwargs to error fallback component in `build_component_from_args`, allowing error state widgets to display metadata. - Adds error rendering UI to JSONViewerWidget: shows alert icon, error message, and styled error container when error is present. - Updates DynamicComponents to spread all component props to JSONViewerWidget for complete error/metadata propagation.
- Update MatplotlibWidget to show a red border, error icon with tooltip, and placeholder message when in error state. - Ensure normal plot rendering is visually unchanged when no error is present. - Renamed `_label` to `label` so that the lable can be displayed - Update json_viewer component to raise exceptions for invalid JSON, ensuring error states are handled via AtomResult.
- Add red border, background, and alert triangle tooltip for error state - Ensure error rendering matches patterns used in other widgets - Refactor markup to prevent layout shift and improve consistency - Error alert appears centered with detailed tooltip on error
- Adds error container styling when `error` or `plotError` is present. - Adds AlertTriangle icon with tooltip describing the error, positioned in the top right corner. - Ensures error content is shown in the same style as other widgets: centered, italic red text. - Unifies error handling so all error messages are presented via the same UX pattern as other widgets.
…roved layout - Adds error state rendering to ProgressWidget. When an error is present, a red border, light background, and alert triangle with tooltip are shown. - Ensures the error icon does not overlap the percent value by keeping layout consistent and adding padding as needed. - Displays a clear error message when progress cannot be shown, but still shows the label and percent. - Minor cleanup: removes unused console.log from BigNumberCard.
- Update SelectboxWidget to apply padding so that select and dropdown contents stay inside the error border, with correct spacing. - Add support for a `label` prop and display it above the select control, matching other widgets’ label style. - Show an alert triangle with tooltip in the error state. - Ensure the select and dropdown maintain a consistent width and do not overflow the error container. - Minor: right-padding on ProgressWidget error state to prevent overlap between error icon and percent text.

Fixes #2735 (Trello: Implement component fail-state rendering)
Description of Changes
This PR implements comprehensive error state rendering across all major frontend widgets and standardizes error propagation from backend Python components to the React UI.
Frontend:
AlertTriangleicon with a tooltip containing the error message, and a textual fallback message in the component body.errorprop, making a best effort to preserv layoutBackend:
errorprop.build_component_from_argsattempts to preserve safe serializable keyword arguments (such astitle,label...) when returning fallback error components, so the frontend can display these values even in error state.Docs / Internal:
