Bugfix — Issue #565: reqView E_WARNING "Undefined property: stdClass::$tproject_id"

Problem

Opening any requirement view page (lib/requirements/reqView.php) generated 3 E_WARNING entries per request in the Event Viewer / events table:

E_WARNING Undefined property: stdClass::$tproject_id
  - in gui/templates_c/...reqViewVersionsViewer.tpl.php

The page rendered correctly, but form action URLs got an empty tproject_id= parameter, falling back to the session project.

Root Cause

lib/requirements/reqView.php → initialize_gui() (line 75) computes $target_id from the requirement's actual project (lines 95-99) but only passes it to getGrants() — never to $gui->tproject_id.

The template reqViewVersionsViewer.tpl references {$gui->tproject_id} in 4 form action URLs (lines 52, 128, 204, 241), all pointing to reqEdit.php?tproject_id={$gui->tproject_id}.

Fix

File: lib/requirements/reqView.php — 1 line added after line 99:

$gui->tproject_id = $target_id;

This assigns the already-computed $target_id (which handles both normal and "alien requirement" cases) to the gui bean, making it available to the template.

Verification

• 0 E_WARNING entries in events table after fix (was 3 before)
• All 4 form action URLs contain tproject_id=1 (was empty before)
• Code review: APPROVED (no side effects, correct placement)

Files Changed

• lib/requirements/reqView.php (+1 line)
