# ✅ Integration Complete - ActionPickerDialog in Action Mapping Form

## Summary

Successfully integrated the ActionPickerDialog into the action mapping form screen. The form now uses the native GeViSet-style action picker instead of dropdowns.

## Changes Made

### 1. Updated Imports
Added new imports for action templates and the ActionPickerDialog:
```dart
import '../../../data/models/action_template.dart';
import '../../../data/services/action_template_service.dart';
import '../../../core/constants/api_constants.dart';
import '../../blocs/auth/auth_bloc.dart';
import '../../blocs/auth/auth_state.dart';
import '../../widgets/action_picker_dialog.dart';
```

### 2. Refactored State Management
**Before:**
- Used `List<TextEditingController>` for output actions
- Used `Map<int, Map<String, dynamic>>` for parameters
- Manual parameter editing dialogs

**After:**
- Uses `List<ActionOutput>` directly
- Loads categories and templates on init
- ActionPickerDialog handles all action selection and parameter editing

**New State Variables:**
```dart
bool _isLoadingTemplates = true;
Map<String, List<String>>? _categories;
Map<String, ActionTemplate>? _templates;
List<ActionOutput> _outputActions = [];
```

### 3. Added Template Loading
```dart
Future<void> _loadActionTemplates() async {
  try {
    // Get auth token from AuthBloc
    final authState = context.read<AuthBloc>().state;
    String? token;
    if (authState is Authenticated) {
      token = authState.token;
    }

    final service = ActionTemplateService(
      baseUrl: ApiConstants.baseUrl,
      authToken: token,
    );

    final categoriesResponse = await service.getActionCategories();
    final templates = await service.getActionTemplates();

    setState(() {
      _categories = categoriesResponse.categories;
      _templates = templates;
      _isLoadingTemplates = false;
    });
  } catch (e) {
    // Handle error...
  }
}
```

### 4. New Action Management Methods

**Add Output Action** - Opens ActionPickerDialog:
```dart
Future<void> _addOutputAction() async {
  if (_categories == null || _templates == null) return;

  final result = await showDialog<ActionOutput>(
    context: context,
    builder: (context) => ActionPickerDialog(
      categories: _categories!,
      templates: _templates!,
    ),
  );

  if (result != null) {
    setState(() {
      _outputActions.add(result);
    });
  }
}
```

**Edit Output Action** - Opens ActionPickerDialog with existing action:
```dart
Future<void> _editOutputAction(int index) async {
  final result = await showDialog<ActionOutput>(
    context: context,
    builder: (context) => ActionPickerDialog(
      categories: _categories!,
      templates: _templates!,
      existingAction: _outputActions[index],
    ),
  );

  if (result != null) {
    setState(() {
      _outputActions[index] = result;
    });
  }
}
```

**Remove Output Action:**
```dart
void _removeOutputAction(int index) {
  setState(() {
    _outputActions.removeAt(index);
  });
}
```

**Reorder Output Actions** (matching native app):
```dart
void _moveOutputActionUp(int index) {
  if (index > 0) {
    setState(() {
      final action = _outputActions.removeAt(index);
      _outputActions.insert(index - 1, action);
    });
  }
}

void _moveOutputActionDown(int index) {
  if (index < _outputActions.length - 1) {
    setState(() {
      final action = _outputActions.removeAt(index);
      _outputActions.insert(index + 1, action);
    });
  }
}
```

### 5. Simplified Submit Form
```dart
void _submitForm() {
  if (_formKey.currentState!.validate()) {
    setState(() {
      _isSaving = true;
    });

    // Validate that at least one output action is provided
    if (_outputActions.isEmpty) {
      // Show error...
      return;
    }

    final mapping = ActionMapping(
      // ...
      outputActions: _outputActions,  // ← Direct use, no transformation needed!
      // ...
    );

    // Submit...
  }
}
```

### 6. Updated UI - Output Actions Section

**New Features:**
- ✅ Loading indicator while templates are loading
- ✅ Empty state message when no actions
- ✅ Cards showing action name and parameters
- ✅ Edit button opens ActionPickerDialog
- ✅ Up/Down buttons for reordering (like native app!)
- ✅ Remove button to delete actions
- ✅ Clean parameter display (read-only, edited via dialog)

**UI Layout:**

## User Experience Improvements

### Before
1. Select action from dropdown (29 hardcoded options)
2. Click "Parameters" to expand
3. Click "+" to add each parameter manually

6. No way to reorder actions

### After
1. Click "Add Output Action" button
2. ActionPickerDialog opens with:
   - Category dropdown (10 categories)
   - Filtered action list (45 actions total)
   - Dynamic parameter fields based on selected action
   - Checkboxes to enable/disable optional parameters
   - Action description shown at bottom

## Next Steps (Optional)

### Phase 3: DataTable Main List View
Replace the card-based list with a DataTable showing:

- Better information density
- Matches native app exactly

### Future Enhancements
1. **Browse buttons for parameters**
   - GCoreServer → Browse from server list
   - PTZ head → Browse from available cameras
   - VideoInput/Output → Browse from channels

2. **Parameter validation**
   - Number fields → Enforce numeric input
   - Range validation where applicable

3. **Search in action list**
   - Quick filter for finding actions in ActionPickerDialog

4. **Input action picker**
   - Use ActionPickerDialog for input actions too
