Menu stops displaying on clicking menu item post upgrading



The menu does not display on clicking menu item post upgrading Pega 7.4 to Pega 8.3.

Error Messages

Not Applicable

Steps to Reproduce

  1. Create a menu item
  2. Include the menu item in the navigation rule
  3. Configure the harness action onClick of the menu item

Root Cause

Harness is non-template and SPA is enabled on dynamic container. When Launch harness is performed on the same harness the Change Tracker creates a new thread object. However, cache holds the stale reference since the menu stops displaying.


This issue was reported as a bug to be remediated in Pega 8.3.2, Pega 8.4 and Pega 8.5 patch releases.
