Tasks: gantt view error

[Ujjvala Collins]

On gantt view Tasks, I tried to drag the task line to extend the end date of the task I got the following traceback:

Hello Ujjvala,

I have checked your issue with updated code for trunk but I didn't face any trace back.
Would you please check attached video and informed us where you faced the problem.

Thanks and waiting for your reply.

Hello Vishal,

Thanks for the video. But I think you haven't checked it properly with all the test cases.

This bug occurs when you clear all the search filters and then try to change the task line. Please check again.

Thanks,
Ujjvala

Could this be requalified because the gantt view has been rewritten, Thanks.

Hello Antony Lesuisse,

Thanks for your reply.

Yes, I agree with you the concurrent update problem has solved that's good but I have faced the different error. Problem occur when I create & start task and assign task work. So I am assigning to web . Would you please see attached video.

Thanks.
