# Custom Request Details Page Fix

## Problem
Custom requests created through the NewRequestWizard were not displaying in the detail page. Instead, users only saw a "Go Back" button.

## Root Cause
1. **Database Lookup Issue**: Dynamic requests created through wizards were only stored in `App.tsx` component state (`dynamicRequests`), not in the static `CUSTOM_REQUEST_DATABASE`
2. **Component Props**: `RequestDetail` and `ClaimManagementDetail` components weren't receiving the `dynamicRequests` prop
3. **Data Flow Gap**: No connection between newly created requests and the detail view components

## Solution Implemented

### 1. Enhanced Request Creation (`App.tsx`)

Updated `handleNewRequestSubmit` to properly create custom request objects:

```typescript
const newCustomRequest = {
  id: requestId,
  title: requestData.title,
  description: requestData.description,
  category: requestData.category,
  subcategory: requestData.subcategory,
  status: 'pending',
  priority: requestData.priority,
  amount: requestData.budget,
  template: 'custom',
  initiator: { ... },
  approvalFlow: [...], // Maps approvers from wizard
  spectators: [...],   // Maps spectators from wizard
  documents: [],
  auditTrail: [...],
  // ... complete request object
};

setDynamicRequests([...dynamicRequests, newCustomRequest]);
```

**Features**:
- Generates unique request ID: `RE-REQ-2024-XXX`
- Maps wizard data to proper request structure
- Creates approval flow from selected approvers
- Adds spectators from wizard
- Initializes audit trail
- Sets proper SLA dates
- Navigates to My Requests page after creation

### 2. Updated Component Props

#### RequestDetail.tsx
```typescript
interface RequestDetailProps {
  requestId: string;
  onBack?: () => void;
  onOpenModal?: (modal: string) => void;
  dynamicRequests?: any[]; // NEW
}
```

#### ClaimManagementDetail.tsx
```typescript
interface ClaimManagementDetailProps {
  requestId: string;
  onBack?: () => void;
  onOpenModal?: (modal: string) => void;
  dynamicRequests?: any[]; // NEW
}
```

### 3. Enhanced Request Lookup Logic

Both detail components now check both static databases AND dynamic requests:

```typescript
const request = useMemo(() => {
  // First check static database
  const staticRequest = CUSTOM_REQUEST_DATABASE[requestId];
  if (staticRequest) return staticRequest;
  
  // Then check dynamic requests
  const dynamicRequest = dynamicRequests.find((req: any) => req.id === requestId);
  if (dynamicRequest) return dynamicRequest;
  
  return null;
}, [requestId, dynamicRequests]);
```

### 4. Intelligent Routing (`App.tsx`)

Updated `renderCurrentPage` for `request-detail` case:

```typescript
case 'request-detail':
  // Check static databases
  const isClaimRequest = CLAIM_MANAGEMENT_DATABASE[selectedRequestId];
  const isCustomRequest = CUSTOM_REQUEST_DATABASE[selectedRequestId];
  
  // Check dynamic requests
  const dynamicRequest = dynamicRequests.find(...);
  const isDynamicClaim = dynamicRequest?.templateType === 'claim-management';
  const isDynamicCustom = dynamicRequest && !isDynamicClaim;
  
  // Route to appropriate component with dynamicRequests prop
  if (isClaimRequest || isDynamicClaim) {
    return <ClaimManagementDetail {...} dynamicRequests={dynamicRequests} />;
  } else {
    return <RequestDetail {...} dynamicRequests={dynamicRequests} />;
  }
```

### 5. Updated handleViewRequest

```typescript
const handleViewRequest = (requestId: string, requestTitle?: string) => {
  setSelectedRequestId(requestId);
  
  // Check all sources
  const isClaimRequest = CLAIM_MANAGEMENT_DATABASE[requestId];
  const isCustomRequest = CUSTOM_REQUEST_DATABASE[requestId];
  const dynamicRequest = dynamicRequests.find(...);
  
  const request = isClaimRequest || isCustomRequest || dynamicRequest;
  setSelectedRequestTitle(requestTitle || request?.title || 'Unknown Request');
  setCurrentPage('request-detail');
};
```

## Data Flow

### Creating a Custom Request

1. User clicks "Raise New Request" → "Custom Request"
2. Fills out NewRequestWizard form:
   - Title
   - Description
   - Category/Subcategory
   - Budget
   - Priority
   - Approvers (multiple)
   - Spectators (multiple)
   - Tagged Participants

3. On Submit:
   - `handleNewRequestSubmit` creates complete request object
   - Adds to `dynamicRequests` state
   - Navigates to My Requests page
   - Shows success toast

4. Viewing the Request:
   - User clicks on request in My Requests
   - `handleViewRequest` finds request in dynamicRequests
   - Routes to `request-detail` page
   - `RequestDetail` component receives `dynamicRequests` prop
   - Component finds request in dynamicRequests array
   - Displays complete request details
