BUG : APEX 24.x : Working Copy merge of Global Page DA corrupts button positions on other pages

fac586Apr 1 2025 — edited Apr 2 2025

Originally discovered on premises in APEX 24.1

Reproduced in APEX 24.2 on apex.oracle.com

Scenario

Application with 3 pages:

  • 0: Global Page
  • 1: Home
  • 2: Standard page
  1. The Global Page contains a Breadcrumb region in the Breadcrumb Bar slot.
  2. Page 2 contains two buttons positioned in the global Breadcrumb region, one in the Close slot, and one in the Create slot.
  3. A working copy is created.
  4. A dynamic action is added to the Global Page, containing a single Execute JS Code step.
  5. The global page DA change is merged into the main app from the working copy.

Issue

Following the merge, the buttons on page 2 previously positioned in the global Breadcrumb region are assigned to an Invalid Slot [Not Rendered] node in the rendering tree, with their individual slots appearing as CLOSE (invalid) and CREATE (invalid) respectively.
