AAI Web UI freezes when manually adding trim points

Products

Issue/Introduction

Symptoms

When a user manually adds a trim point to a jobstream (searching for a job, adding it, and clicking Save), the following occurs:

• The UI displays a loading spinner and becomes unresponsive for several minutes.
• The user cannot switch tabs or perform other actions in AAI until the process finishes.
• The browser may occasionally prompt that the page is unresponsive.

Environment

Product: Automation Analytics & Intelligence (AAI) 24.4.1 and earlier
Component: Web UI

Cause

This is caused by product defect DE203763. In AAI version 24.4.0, the jobstream run history rebuild triggered by manual trimming is handled as a synchronous foreground task. The Web UI thread is blocked until the database updates are complete.

Resolution

This issue is resolved in AAI version 24.4.2 (Service Pack).

In version 24.4.2, the rebuild process has been moved to a background task. This allows the user to continue working immediately after saving, while the history rebuild completes independently.

Workaround: If an upgrade is not immediately possible, users must wait for the "Updating" spinner to clear naturally or refresh the browser tab (though refreshing may not stop the backend rebuild process).
