[REACT] Bryntum gantt: When we change existing Constraint type then it is throwing exception

[sagars93]

Hello team,
When we change existing Constraint type in Bryntum Gantt then it is throwing exception like:
Uncaught (in promise) Error: Unknown identifier ClassDefEx.$.assigned

Unknown id3.png (181.5 KiB) Viewed 315 times

Unknown id1.png (85.26 KiB) Viewed 318 times

Unknown id2.png (50.53 KiB) Viewed 318 times

How to resolve this issue.

(It may be caused by Bryntum not being able to schedule the task based on the existing constraints and throwing an error.)

Thanks in advance.

How can we reproduce it? I tried our https://localhost/bryntum-suite/Gantt/examples/advanced/ but it looks that you use the different data so I couldn't reproduce it.

Hi sagars93,

Could you please try it yourself?
I used the task you provided and tried to change constraintType. All works well to me.

Please, provide clear steps to reproduce and the environment where we can reproduce it.
If it is possible, modify one of our examples, zip and attach the app here.

Thanks!
