Correspondence Module Refactoring Report

Date: 2025-12-11 Objective: Fix data display issues and align Correspondence Module with user requirements (Revision-based List).

🛠 Fixes & Changes

1. Revision-Based List View

• Issue: The Correspondence List was displaying one row per Document, hiding revision history.
• Fix: Refactored CorrespondenceService.findAll to query CorrespondenceRevision as the primary entity.
• Outcome: The list now displays every revision (e.g., Doc-001 Rev A, Doc-001 Rev B) as separate rows. Added "Rev" column to the UI.

2. Correspondence Detail Page

• Issue: Detail page was not displaying Subject/Description correctly (showing "-") because it wasn't resolving the currentRevision correctly or receiving unwrapped data.
• Fix:
  • Updated CorrespondenceDetail to explicitly try finding isCurrent revision or fallback to index 0.
  • Updated useCorrespondence (via correspondence.service.ts) to correctly unwrap the NestJS Interceptor response { data: { ... } }.
• Outcome: Detail page now correctly shows Subject, Description, and Status from the current revision.

3. Edit Functionality

• Issue: Clicking "Edit" led to a 404/Blank page.
• Fix:
  • Created app/(dashboard)/correspondences/[id]/edit/page.tsx.
  • Refactored CorrespondenceForm to accept initialData and supporting "Update" mode (switching between createMutation and updateMutation).
• Outcome: Users can now edit existing DRAFT correspondences.
