Component Behavior Issues

Component Interactions Not Working

Symptom

Components don't communicate or actions don't trigger as expected.

Common Causes and Solutions

1. Event Configuration Issues

Check: Events must be configured appropriately on both sending and receiving components.

Solution:

• Verify event names match exactly (case-sensitive)

• Check event is being fired by source component

• Ensure target component is listening for correct event

• Test event flow in isolation

2. Action Sequence Problems

Check: Actions may be in wrong order or missing steps.

Solution:

• Review action sequence in component builder

• Verify each action has correct configuration

• Test actions individually before chaining

• Check for conditional logic that may prevent execution

3. Data Mapping Errors

Check: Data being passed between components may not match expected format.

Solution:

• Verify data types match (text to text, number to number)

• Check field mappings are correct

• Use console logging to debug data flow

• Validate data transformation logic

Styling Not Applying

Symptom

Custom CSS or styling doesn't appear on component.

Common Causes and Solutions

1. CSS Specificity Issues

Check: Lightning base styles may override custom styles.

Solution:

• Increase CSS specificity

• Use !important flag sparingly

• Apply styles to specific component classes

• Check browser inspector for style conflicts

2. Syntax Errors in CSS

Check: Invalid CSS syntax prevents styles from applying.

Solution:

• Validate CSS syntax

• Check for missing semicolons or brackets

• Test CSS in browser developer tools first

• Remove styles one by one to identify problem

3. Lightning Design System Conflicts

Check: SLDS classes may conflict with custom styles.

Solution:

• Use SLDS utility classes when possible

• Scope custom CSS to avoid conflicts

• Test styling with and without SLDS classes

• Review SLDS documentation for compatible approaches

Data Not Refreshing

Symptom

The component displays outdated data and fails to update when records are changed.

Common Causes and Solutions

1. No Refresh Mechanism

Check: Component may need manual refresh configuration.

Solution:

• Add refresh button or action

• Implement refresh all queries interaction

• Configure refresh on specific events

2. Caching Issues

Check: Browser or component caching may show old data.

Solution:

• Clear browser cache

• Add cache-busting parameters

• Implement proper cache invalidation

• Test in incognito/private mode
