App crashes on editing Gantt chart task

[Prabhat Thakur]

We are encountering an issue where the application crashes when editing tasks within the Gantt chart component. This behavior is observed consistently, particularly when interacting with larger datasets.

Issue Summary:

The application becomes unresponsive and eventually crashes when a user attempts to edit a task in the Gantt chart.

Prabhat,

 

Thanks for your patience.

 

We are glad to announce that our patch release (v30.1.38) is rolled out successfully. In this release, we have added the fix for the reported issue.

 

Please upgrade to the latest version packages to resolve this issue "When editing Gantt chart gets unresponsive with multiple dependency connection in Angular | Feedback Portal".

 

Root Cause - The issue was caused by missing checks for already processed tasks and unconnected predecessors, leading to unnecessary recursion. Adding those checks prevents redundant or infinite calls.
