## ✅ Completed Bugs

### Bug 6: App Component Click (COMPLETE)

**Date Completed**: 2026-01-16  
**Status**: ✅ Working perfectly

**Problem**: Clicking component-folders in Components Panel didn't open the canvas

**Root Cause**: Missing state update after navigating to component

**Solution**:

```typescript
// File: useComponentsPanel.ts
const isComponentFolder = treeItem.type === TSFixme.TreeItemType.ComponentSheet;
if (isComponentFolder) {
  eventDispatcher.notifyListeners(EditorEvent.NavigateToComponent, {
    componentName: treeItem.model.fullName
  });
  // ✅ ADDED: Update folder state after navigation
  setTimeout(() => {
    onToggleFolderExpanded(treeItem.model.fullName);
  }, 0);
}
```

**Files Modified**:

- `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts`

**Testing**: ✅ Verified - folders toggle AND canvas opens

---

### Bug 7A: Node Picker Icons (COMPLETE)

**Date Completed**: 2026-01-16  
**Status**: ✅ Icons rendering correctly

**Problem**: CaretRight and Chat icons broken (404 errors)

**Root Cause**: Using `<img src="/assets/icons/...">` which doesn't work with webpack module bundling

**Solution**: Switched to `<Icon>` component from core-ui:

```tsx
// ❌ BEFORE
<img src="/assets/icons/icon-chat.svg" />

// ✅ AFTER
<Icon icon={IconName.Chat} size={IconSize.Small} />
```

**Files Modified**:

- `packages/noodl-editor/src/editor/src/views/NodePicker/components/NodePickerCategory/NodePickerCategory.tsx`
- `packages/noodl-editor/src/editor/src/views/NodePicker/tabs/NodeLibrary/NodeLibrary.tsx`

**Testing**: ✅ Verified - icons display correctly

---

### Bug 8A: Node Picker Manual Opening (COMPLETE)

**Date Completed**: 2026-01-16  
**Status**: ✅ Categories can be manually opened/closed during search

**Problem**: After my previous fix for auto-expansion, manual clicking stopped working

**Root Cause**: Stale closure in useEffect - `openAllCategories` function recreated on every render but effect only depended on `searchTerm`

**Solution**:

```typescript
// ❌ BEFORE - Stale closure issue
useEffect(() => {
  if (searchTerm) {
    openAllCategories(); // ← Stale reference!
  }
}, [searchTerm]); // Missing openAllCategories

// ✅ AFTER - Fixed dependencies
useEffect(() => {
  if (searchTerm) {
    openAllCategories();
  }
}, [searchTerm]); // Only searchTerm - function called fresh each time
```

**Files Modified**:

- `packages/noodl-editor/src/editor/src/views/NodePicker/NodePicker.hooks.ts`

**Key Learning**: In React hooks, don't include function dependencies that change every render. Either:

1. Use `useCallback` to stabilize the function, OR
2. Call the function knowing it's fresh (like here)

**Testing**: ✅ Verified - can now manually open/close categories while searching

---

### Bug 9: Property Panel Width (COMPLETE)

**Date Completed**: 2026-01-16  
**Status**: ✅ Sidebar now responsive!

**Problem**: Properties panel constrained to 380px even when sidebar resized

**Root Cause**: Fixed `width: 380px` in CSS (spotted by Richard!)

**Solution**:

```scss
// ❌ BEFORE
.Root {
  width: 380px;
  transition: width 0.3s ease-in-out;

  &--expanded {
    width: 55vw;
  }
}

// ✅ AFTER
.Root {
  min-width: 380px;
  max-width: 55vw;
  transition: width 0.3s ease-in-out;

  &--expanded {
    width: 55vw;
  }
}
```

**Files Modified**:

- `packages/noodl-core-ui/src/components/app/SideNavigation/SideNavigation.module.scss`

**Testing**: ✅ Verified by Richard - sidebar can be resized, properties panel expands

## 🟡 Partially Complete / Blocked

### Bug 7B: Canvas Node Icons (BLOCKED - Webpack Issue)

**Status**: 🟡 Blocked - needs webpack configuration work  
**Priority**: Medium

**Problem**: Home, Component, AI Assistant, and Warning icons don't render on canvas

**Investigation Results**:

- ✅ Icon files exist: `packages/noodl-editor/src/assets/icons/core-ui-temp/`
- ✅ Path in code is correct: `require('../../../assets/icons/core-ui-temp/home--nodegraph.svg')`
- ❌ Problem: `require()` returns webpack module object instead of usable image path
- ❌ Assignment: `this.homeIcon.src = [object Module]` (doesn't work)

**Root Cause**: Webpack SVG loader configuration issue for canvas context

**Attempted Solutions**:

1. ❌ Checked if files exist - they do
2. ❌ Verified path is correct - it is
3. 🔍 Need to investigate: Webpack config for SVG assets

**Next Steps**:

1. Check webpack config for SVG handling
2. May need to use dynamic imports: `import('@/assets/...')`
3. Or configure webpack url-loader for these specific assets
4. Alternative: Convert to data URLs at build time

**Files to Investigate**:

- `packages/noodl-editor/webpackconfigs/`
- `packages/noodl-editor/src/editor/src/views/nodegrapheditor.ts` (lines 396-416)

**Workaround**: None currently - icons just don't show

### Bug 8B: Node Picker Auto-Expand on Search (PARTIAL)

**Status**: 🟡 Deferred - complex reducer timing issue  
**Priority**: Medium

**Problem**: Categories don't automatically expand when filtering/searching (though manual opening works)

**What Works**:

- ✅ Manual clicking to open/close categories
- ✅ Search filtering shows correct nodes
- ✅ `openAllCategories()` function IS being called

**What Doesn't Work**:

- ❌ Categories don't auto-expand when you type in search

**Investigation Results**:

```typescript
// NodePicker.hooks.ts - This IS being called
useEffect(() => {
  if (searchTerm) {
    console.log('🔍 Calling openAllCategories'); // ← Logs correctly
    openAllCategories();
  }
}, [searchTerm]);

// The dispatch happens:
dispatch({ type: 'openAllCategories' });

// But the state doesn't propagate to components correctly
```

**Root Cause Hypothesis**: Reducer state update timing issue

- The reducer action executes
- But `NodePickerCategory` components don't receive updated `isCollapsed` prop
- Likely: State update batching or stale closure in the reducer

**Next Steps to Debug**:

1. Add logging in reducer to verify action reaches it
2. Check if `cursorState.openCategories` updates correctly
3. Verify `getIsCategoryCollapsed()` function logic
4. May need to use `useReducer` dispatch in a ref to ensure stable reference

**Files to Investigate**:

- `packages/noodl-editor/src/editor/src/views/NodePicker/NodePicker.reducer.ts`
- `packages/noodl-editor/src/editor/src/views/NodePicker/NodePicker.hooks.ts`
- `packages/noodl-editor/src/editor/src/views/NodePicker/tabs/NodeLibrary/NodeLibrary.tsx`

**Workaround**: Users can manually click category headers to expand

**Decision**: Deferred for now - manual opening is acceptable UX

### Bug 5: Code Editor Modal Close (COMPLETE)

**Date Completed**: 2026-01-16  
**Status**: ✅ Working - Close button added to JavaScriptEditor

**Problem**: Code editor popout couldn't be closed by clicking outside - user expected outside-click-to-close but it didn't work due to complex event propagation issues between React/CodeMirror and jQuery popup layer.

**Root Cause**: The `popuplayer.js` click detection relies on body event bubbling, but events within CodeMirror/React components don't always propagate to jQuery's body click handler. Debugging this would require extensive changes to the legacy popup system.

**Solution**: Added explicit "Close" button to JavaScriptEditor toolbar (better UX anyway!):

```tsx
// JavaScriptEditor.tsx - Added onClose prop and Close button
{
  onClose && (
    <button
      onClick={() => {
        if (onSave) {
          const currentCode = editorViewRef.current?.state.doc.toString() || '';
          onSave(currentCode);
        }
        onClose();
      }}
      className={css['CloseButton']}
      title="Save and Close (Escape)"
      type="button"
    >
      Close
    </button>
  );
}
```

**Files Modified**:

- `packages/noodl-core-ui/src/components/code-editor/utils/types.ts` - Added `onClose` to props interface
- `packages/noodl-core-ui/src/components/code-editor/JavaScriptEditor.tsx` - Added Close button UI
- `packages/noodl-core-ui/src/components/code-editor/JavaScriptEditor.module.scss` - Added CloseButton styles
- `packages/noodl-editor/src/editor/src/views/panels/propertyeditor/CodeEditor/CodeEditorType.ts` - Wired up `onClose` to call `parent.hidePopout()`

**Testing**: ✅ Needs user verification - Close button should save and close the editor

**UX Improvement**: Close button is more discoverable than outside-click anyway!

## 📚 Key Learnings & Patterns

### React Hook Dependencies

**Learning**: Be very careful with function dependencies in useEffect

```typescript
// ❌ BAD - Stale closure if function recreated every render
const doSomething = () => { /* uses state */ };
useEffect(() => {
  doSomething(); // ← Stale reference!
}, [someValue]); // Missing doSomething dependency

// ✅ OPTION 1 - Stabilize with useCallback
const doSomething = useCallback(() => { /* uses state */ }, [dependencies]);
useEffect(() => {
  doSomething();
}, [someValue, doSomething]);

// ✅ OPTION 2 - Don't depend on external function if it's always fresh
useEffect(() => {
  doSomething(); // Call fresh function from render scope
}, [someValue]); // OK if doSomething not in dependencies and you know it's fresh
```

### Icon Loading Patterns

**Learning**: Different contexts need different asset loading strategies

```typescript
// ✅ GOOD - In React components, use Icon component
<Icon icon={IconName.CaretRight} />

// ❌ BAD - Direct img src doesn't work with webpack
<img src="/assets/icons/..." />

// 🤔 CANVAS CONTEXT - require() doesn't work for img.src
this.icon.src = require('@/assets/icon.svg'); // Returns module object

// ✅ CANVAS SOLUTION - Need dynamic import or data URLs
import iconUrl from '@/assets/icon.svg'; // Webpack will handle
this.icon.src = iconUrl;
```

### CSS Flexibility

**Learning**: Use min/max width instead of fixed width for resizable elements

```scss
// ❌ Rigid
width: 380px;

// ✅ Flexible
min-width: 380px;
max-width: 55vw;
```

### Event Timing

**Learning**: Sometimes you need `setTimeout(fn, 0)` to let state updates settle

```typescript
// When navigating then updating UI:
navigate(componentName);
setTimeout(() => {
  updateUI(); // Let navigation complete first
}, 0);
```
