  - Prevents 'Cannot read property toString of null' runtime errors
  - Extracts fieldKey and fieldData into variables for better readability
  - Only calls toString() when fieldData exists and value is not null

- Add debug mode attribute (1.1 - partial)
  - Added 'debugMode' Boolean attribute (default: false)
  - Allows users to opt-in to console logging for debugging
  - Disabled by default for performance and security

Documentation:

Priority 1 Fix (1.1): Remove/Reduce Console Logging

Changes:
- Created debugLog() helper function in detectAndLaunchHelper.js
  - Checks debugMode attribute before logging
  - Supports optional data parameter for structured logging
  - Only logs when debugMode is explicitly enabled (default: false)

- Replaced all console.log statements with conditional debug logging
  - Controller: 8 console.log statements → helper.debugLog() calls
  - Helper: 12 console.log statements → this.debugLog() calls
  - Total: 20 debug statements now conditional on debugMode

- Critical error logging preserved
  - Changed error logging to console.error() (always logs)
  - Catch block errors in workspace API calls
  - ERROR changeType events in recordUpdated handler
  - Ensures critical issues are always logged for troubleshooting

Benefits:
- Performance: No console logging overhead when debugMode=false (default)
- Security: Internal component logic not exposed unless explicitly enabled
- Maintainability: Centralized logging logic in debugLog() helper
- User Experience: Users can enable debug mode when troubleshooting

Files changed:
- detectAndLaunchController.js: Replaced 8 console.log with debugLog calls
- detectAndLaunchHelper.js: Added debugLog helper, replaced 12 console.log calls
Priority 1 Fix (1.2): Fix Loose Equality Checks

Changes:
- detectAndLaunchHelper.js:
  - Line 48: Changed 'flowApiName == null || flowApiName == undefined' to '!flowApiName'
    - Uses truthiness check which is cleaner and more idiomatic
    - Handles null, undefined, empty string, 0, false consistently
  - Line 51: Changed 'launchMode == "Modal"' to 'launchMode === "Modal"'
    - Prevents unexpected type coercion
    - Ensures exact string match
  - Line 65: Changed 'flowApiName != null && flowApiName != undefined' to 'flowApiName'
    - Simplified redundant check (already verified flowApiName is truthy above)
    - More readable and maintainable

- detectAndLaunchController.js:
  - Line 39: Changed 'fieldChange != null && fieldValue != null' to strict checks
    - Now uses '!== null && !== undefined' for both fieldChange and fieldValue
    - Explicitly checks for both null and undefined (common in Lightning attributes)
    - Prevents type coercion issues
  - Line 51: Changed 'fieldData.value != null' to 'fieldData.value !== null'
    - Uses strict equality for null check
    - More explicit about checking for null specifically

Benefits:
- Prevents unexpected type coercion bugs
- More explicit and readable code
- Follows JavaScript best practices
- Reduces potential for subtle bugs from loose equality

Files changed:
- detectAndLaunchHelper.js: 3 loose equality checks fixed
- detectAndLaunchController.js: 2 loose equality checks fixed
Priority 1 Fix (1.4): Add Error Handling for Flow Launch

Changes:
- Added comprehensive error handling around flow.startFlow() call
  - Wrapped flow.startFlow() in try-catch block to handle runtime errors
  - Added validation to check if flow component exists before calling startFlow
  - Added validation to ensure flowApiName is valid before attempting to start flow

- Error handling improvements:
  - Try-catch block catches any errors during flow.startFlow() execution
  - Logs detailed error information using console.error (always logs)
    - Error object
    - Flow API name for context
    - Error message/details
  - Automatically closes modal if flow fails to start (prevents stuck modal)
  - Provides clear error messages for missing flow component or invalid flow name

- Validation checks:
  - Checks if flow component exists (component.find('flow') returns valid component)
  - Checks if flowApiName is truthy before attempting to start
  - Separate error messages for each validation failure

Benefits:
- Prevents unhandled exceptions from crashing component
- Provides clear error messages for troubleshooting
- Gracefully handles errors by closing modal
- Better user experience when flows fail to start
- Helps developers identify configuration issues

Files changed:
- detectAndLaunchHelper.js: Added try-catch and validation around flow.startFlow()
… literals

Priority 2 Fix (2.2): Improve Code Readability with Template Literals

Changes:
- Replaced all string concatenation with ES6 template literals for better readability
  - All targetUrl constructions now use template literals
  - All debug log string concatenations converted to template literals

- Specific changes:
  - Line 34: targetUrl in REMOVED event handler
    - Before: '/flow/' + component.get("v.targetFlowName") + '?recordId=' + component.get("v.recordId")
    - After: `/flow/${component.get("v.targetFlowName")}?recordId=${component.get("v.recordId")}`

  - Line 99: targetUrl in console subtab navigation
    - Same pattern updated

  - Line 113: targetUrl in standard window.open
    - Same pattern updated

- Debug log improvements:
  - Line 23: currentUrl debug log
  - Line 29: changeType debug log (CHANGED event)
  - Line 35: targetURL debug log (REMOVED event)
  - Line 38: changeType debug log (LOADED event)
  - Line 46: changeType debug log (callFlow)
  - Line 94: console navigation debug log
  - Line 114: targetURL debug log (standard window.open)

Benefits:
- More readable and maintainable code
- Modern JavaScript best practices (ES6 template literals)
- Easier to modify URL patterns
- Consistent code style throughout helper file
- Reduced chance of syntax errors from missing + operators

Files changed:
- detectAndLaunchHelper.js: 10 string concatenations replaced with template literals
…er method

Priority 2 Fix (2.3): Refactor Field Watching Logic

Changes:
- Created checkFieldValueMatch() helper method in detectAndLaunchHelper.js
  - Extracts complex nested conditional logic from recordUpdated controller method
  - Encapsulates all field value matching logic in a single, testable method
  - Returns boolean indicating if field value matches configured criteria
  - Includes comprehensive JSDoc documentation

- Simplified recordUpdated() method in detectAndLaunchController.js
  - Reduced from 30+ lines of nested conditionals to simple helper call
  - Much more readable and maintainable
  - Clear separation of concerns

- Helper method logic:
  - Validates fieldChange and fieldValue are configured
  - Only processes CHANGED events (conditional launch only works on edits)
  - Validates changedFields exists
  - Safely extracts and compares field values
  - Handles null/undefined values gracefully
  - Returns true only when field value matches expected value

- Additional improvements:
  - Fixed remaining string concatenation in debug log (template literal)
  - Improved code organization and maintainability

Benefits:
- Improved code readability and maintainability
- Easier to test field matching logic in isolation
- Reduced complexity in controller method
- Better separation of concerns
- Reusable helper method for future enhancements

Files changed:
- detectAndLaunchController.js: Simplified recordUpdated method (30 lines reduced)
- detectAndLaunchHelper.js: Added checkFieldValueMatch helper method (43 lines added)
Priority 2 Fix (2.5): Fix Modal Height Issue

Changes:
- Removed hardcoded 600px height from modal container
  - Removed inline style="height: 600px;" from div wrapper
  - Changed class from "demo-only" to "slds-modal-container" for better semantics

- Added responsive CSS classes and styles
  - Added slds-modal__container--responsive class to modal container
  - Implemented responsive sizing with max-width and max-height
  - Modal now adapts to viewport size (90vw x 90vh on desktop, 95vw x 95vh on mobile)

- Added responsive CSS rules in detectAndLaunch.css
  - Base responsive sizing: max-width 90vw, max-height 90vh
  - Content area is scrollable if needed (max-height calc(90vh - 8rem))
  - Mobile breakpoint (@media max-width: 48rem) for smaller screens
  - Ensures modal works well on all screen sizes

- Benefits:
  - Modal adapts to different screen sizes automatically
  - Content is scrollable if it exceeds viewport
  - Better user experience on mobile devices
  - No more fixed height that may cut off content
  - Follows SLDS responsive design patterns

Files changed:
- detectAndLaunch.cmp: Removed fixed height, added responsive classes
- detectAndLaunch.css: Added responsive CSS rules and media queries
Priority 3 Enhancement (3.3): Add JSDoc Documentation

Changes:
- Added comprehensive JSDoc comments to all functions in both controller and helper files
  - All functions now have proper documentation with parameter descriptions
  - Includes return types where applicable
  - Documents function purpose and behavior

- Controller functions documented:
  - doInit: Initializes component field list for recordData watching
  - openModal: Opens modal dialog for flow execution
  - closeModal: Closes modal dialog
  - flowStatusChange: Handles flow status changes and closes modal when finished
  - recordUpdated: Main handler for record update events, determines which flow to launch

- Helper functions documented:
  - debugLog: Already had JSDoc (no changes)
  - checkFieldValueMatch: Already had JSDoc (no changes)
  - processChangeEvent: Added JSDoc documenting record change event processing

  - Additional context about event parameters and their structure

Benefits:
- Improved code maintainability and readability
- Better IDE support with autocomplete and type hints
- Easier for new developers to understand the codebase
- Follows JavaScript documentation best practices
- Enables better tooling support (JSDoc generators, etc.)

Files changed:
- detectAndLaunchController.js: Added JSDoc to 5 functions
- detectAndLaunchHelper.js: Added JSDoc to 2 functions (2 already had docs)
Priority 3 Enhancement (3.4): Update API Version

Changes:
- Updated API version from 48.0 (2020) to 65.0 (Winter '26)
  - Enables access to latest Salesforce platform features
  - Ensures compatibility with current Salesforce releases
  - Follows Salesforce best practices for API version management

- Benefits:

Priority 3 Enhancement (3.5): Add User Feedback for Errors

Changes:
- Added lightning:notificationsLibrary to component for toast notifications
  - Added notifLib aura:id for accessing notifications library

- Created showErrorToast() helper method
  - Displays error toast notifications to users
  - Uses sticky mode so errors remain visible
  - Also logs to console for debugging purposes
  - Includes JSDoc documentation

- Replaced console.error with user-friendly toast notifications:
  - Flow start errors: Shows specific error message with flow name
  - Flow component not found: Configuration error message
  - Flow API name missing: Configuration error message
  - Console navigation errors: Navigation error message
  - Record update errors: Shows record error message

- Error handling improvements:
  - User-facing errors now show toast notifications
  - Console errors still logged for debugging
  - Better user experience with visible error feedback
  - Clear, actionable error messages

- Benefits:
  - Users can see errors without opening browser console
  - Better user experience with visible feedback
  - Errors are sticky so users don't miss them
  - Still maintains console logging for developers
  - Professional error handling

Files changed:
- detectAndLaunch.cmp: Added lightning:notificationsLibrary
- detectAndLaunchHelper.js: Added showErrorToast method, updated error handling
- detectAndLaunchController.js: Updated ERROR event handling to show toast
Bug Fix: Prevent runtime error when fieldData.value is undefined

Issue:
- Line 70 only checked for null: fieldData.value === null
- If fieldData.value was undefined, the check would pass
- Line 75 would then call .toString() on undefined, causing runtime error

Fix:
- Added explicit check for undefined: fieldData.value === undefined
- Now checks both null and undefined before calling toString()
- Prevents 'Cannot read property toString of undefined' errors

Changes:
- detectAndLaunchHelper.js line 70: Added undefined check in checkFieldValueMatch function
- Updated comment to reflect both null and undefined checks

This ensures the function safely handles all falsy value scenarios before
attempting to convert the field value to a string.
… match

Bug Fix: Component was launching flows even when field conditions were configured but not met

Issue:
- When fieldChange and fieldValue are configured, component should only launch flows when the field value matches
- Refactored code had a logic flaw: if checkFieldValueMatch returned false, the else block would unconditionally launch flows based on changeType
- This caused flows to launch even when field conditions were configured but the value didn't match

Fix:
- Added explicit check to determine if field conditions are configured
- If field conditions ARE configured and value matches: launch flow (correct behavior)
- If field conditions ARE configured but value doesn't match: return early, don't launch any flow (fixes bug)
- If field conditions are NOT configured: proceed with normal flow launching logic (preserves existing behavior)

Changes:
- detectAndLaunchController.js: Added fieldConditionsConfigured check and early return when conditions don't match
- Restores the original behavior where nested conditionals prevented launching when field conditions were configured but not met

This ensures conditional field-based launching works correctly and only launches flows when the configured field value matches.

Bug Fix: Field conditions were blocking deleteFlowName and loadFlowName flows

Issue:
- When fieldChange and fieldValue were configured, the code would return early
  for any event that didn't match field conditions, including REMOVED and LOADED events
- This prevented deleteFlowName and loadFlowName from launching even though
  field-based conditions should only apply to CHANGED events
- Users expecting delete or load flows to trigger found them blocked if they
  had also configured field-based conditional triggering

Fix:
- Field conditions now only apply to CHANGED events
- Added check: fieldConditionsConfigured && eventParams.changeType === "CHANGED"
- For REMOVED and LOADED events, even if field conditions are configured,
  the normal flow launching logic proceeds
- This allows deleteFlowName and loadFlowName to work correctly regardless
  of whether field conditions are configured

Changes:
- detectAndLaunchController.js line 76: Added changeType check to field
  condition logic
- Field conditions now only evaluated for CHANGED events
- REMOVED and LOADED events bypass field condition checks and proceed with
  normal flow launching logic

This ensures that field-based conditional launching only affects CHANGED
events, while REMOVED and LOADED events continue to work as expected.
Enhancement: Improve component branding and identification

Changes:
- Added master label 'Detect and Launch Flow' to component markup
- Created custom SVG icon representing detection and flow launching
- Icon design includes:
  * Radar/detection circles (left) - represents record change detection
  * Arrow indicator (center) - represents launch/trigger action
  * Flow symbol (bottom) - represents screen flow execution
- Uses Salesforce blue (#0176D3) background with white elements
- Replaces generic 'A' icon with meaningful visual representation

Files changed:
- detectAndLaunch.cmp: Added label attribute to component
- detectAndLaunch.svg: Created new custom icon design

This improves the component's visibility and identification in the
Lightning App Builder and component library.

Fix: Aura components don't support label attribute on component tag

Issue:
- Added label attribute to component tag which caused deployment failure
- Aura components don't support label attribute like LWC components do
- Error: Invalid attribute "label" (1:142)

Fix:
- Removed label attribute from component tag
- Updated description in .cmp-meta.xml to be more descriptive
- Component will be identified by its API name in Lightning App Builder
- Custom SVG icon still provides visual identification

Changes:
- detectAndLaunch.cmp: Removed label attribute
- detectAndLaunch.cmp-meta.xml: Updated description to 'Detect and Launch Flow - Automatically detects record changes and launches screen flows based on configurable triggers'

Note: Aura components are identified by their API name in Lightning App Builder.
The custom SVG icon provides visual identification.
