AAI Web UI freezes after disabling auto-trim and re-editing jobstream

Products

• Automation Analytics & Intelligence

Issue/Introduction

Users experience a permanent hang or unresponsiveness in the Automation Analytics & Intelligence (AAI) Web UI when performing specific jobstream configuration changes:

• Disabling the "Auto-trim" setting and clicking Save.
• The UI shows the expected "Updating..." spinner for the initial rebuild.
• If the user attempts to click the "Edit Jobstream" button again while the background rebuild is still in progress, the UI becomes permanently locked on the "Updating..." screen.
• The browser may prompt that the page is unresponsive, and the user must refresh the tab to regain control.

Environment

• Product: Automation Analytics & Intelligence (AAI)
• Version: 24.4.0
• Component: Web UI

Cause

This behavior is a result of a product defect (DE203765). In version 24.4.0, certain jobstream rebuild operations (triggered by trimming or forecasting changes) are executed as synchronous foreground tasks. If a subsequent edit request is sent before the previous database and engine updates are finalized, the Web UI thread becomes blocked, preventing further interaction.

Resolution

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

In the fixed versions, the jobstream rebuild process is moved to a background task, ensuring the Web UI remains responsive even if the user attempts to re-edit the jobstream immediately after saving.
