Bryntum Support Forums

Hi at all,

I have faced an issue I don't know how to deal with, maybe you can help me.
Sometimes I get an error like this:

Uncaught (in promise) Error: Unknown identifier ClassDefEx-project-project_402.$.assigned

I really dont know what to do with this one, if you have any idea I would appreciate.

Many thanks,

How can we reproduce this? Do you see it in our demos too?

I guess it depends on the predecessors/successors but I can not reproduce it, it does not happen all the time, thats the problem.

Might be caused by a scheduling conflict. If you face it again please provide us w/ the dataset used so we could try reproducing the issue.
