## Bug Fixes During Refactoring

### Critical Fixes
1. ✅ **Null date error** in performance/self-assessments/show.blade.php
   - Issue: `$selfAssessment->assessment_date->format()` threw error when null
   - Fix: Used null-safe operator `$selfAssessment->assessment_date?->format() ?? 'No date'`

2. ✅ **Null array errors** for achievements, challenges, goals
   - Issue: `@foreach($selfAssessment->achievements as $achievement)` threw error when null
   - Fix: Added null checks: `@if($selfAssessment->achievements && count($selfAssessment->achievements) > 0)`

3. ✅ **Undefined function `can()`** in breadcrumbs
   - Issue: `can('view_employees')` not available in array context
   - Fix: Changed to `auth()->user()->can('view_employees')`

4. ✅ **Carbon type error** in loan calculations
   - Issue: `addMonths()` received string instead of int
   - Fix: Cast to int: `->addMonths((int) $loan->repayment_period_months)`

5. ✅ **Undefined variable $icon** in stat-card
   - Issue: Component used without icon prop
   - Fix: Made icon optional with default null, added `color` prop alias

6. ✅ **Parse errors** from unclosed components
   - Issue: Components not properly closed
   - Fix: Properly closed all component tags

7. ✅ **Array offset errors** in subscription views
   - Issue: Accessing array offset on boolean
   - Fix: Fixed prop passing and added null-safe operators

### Component Improvements
1. ✅ Made `stat-card` icon optional
2. ✅ Added `color` prop alias for `type`
3. ✅ Made `subscription-usage` support both organization and usage props
4. ✅ Fixed `detail-row` table wrapping
5. ✅ Improved null-safe array access throughout

## Best Practices Established

### 1. Component Usage Patterns
```blade
<!-- Page structure -->
<x-breadcrumb :items="$breadcrumbs" />
<x-alert />

<!-- Forms -->
<form method="POST" action="{{ route('model.store') }}">
    @csrf
    <x-form.input name="field" label="Label" required />
    <x-form.button-group 
        cancelUrl="{{ route('model.index') }}"
        submitText="Save" />
</form>

<!-- Show views -->
<x-info-card title="Section Title" icon="icon-name">
    <table class="table table-borderless">
        <x-detail-row label="Field" :value="$model->field" />
    </table>
</x-info-card>
```

### 2. Null Safety
Always use null-safe operators for nullable fields:
```blade
{{ $model->date?->format('Y-m-d') ?? 'N/A' }}
{{ $model->relationship?->name ?? 'Not assigned' }}
@if($model->array && count($model->array) > 0)
    @foreach($model->array as $item)
        <!-- ... -->
    @endforeach
@endif
```

### 3. Component Composition
Components can be nested for powerful combinations:
```blade
<x-detail-row label="Status">
    <x-status-badge :status="$model->status" />
</x-detail-row>
```

## Component Quick Reference

### Most Used Components

#### Page Header

    name="title" 
    label="Title" 
    required 
    placeholder="Enter title"

```

#### Empty State
```blade
<x-empty-state icon="inbox" title="No items found">
    <x-slot:actions>

    </x-slot:actions>
</x-empty-state>
```
