BPM process start issue


I am trying to create a process task and want to assign the task to my select users but

I am not able to assign the task to the selected users.

The following error is showing when trying to submit the task

PropertyNotFoundException: Cannot resolve identifier 'sid9840850060DC4D8EBE08A47907EFB79D_result'

I am not able to find the solution Please suggest me how to solve above error.


What do you mean by “trying to create a process task”? Normally you don’t have to create the ProcTask entity manually. It will be created automatically. I’ve already mentioned it in this topic: https://www.cuba-platform.com/discuss/t/bpm-issue.
I can’t say anything about the error based on the information you provided. Can you please attach a small demo project that reproduces your issue.
