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The component displays outdated data and fails to update when records are changed.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