Re: while creating Problem report we face "wt.org.WTGroup cannot be cast to wt.org.WTUser"

You have an error in your workflow expression where you are receiving a WTGroup and passing it to WTUser group. I will look at com.godrej.WorkflowHelper.checkSetupParticipant method and at the entry point to this in the workfow

Re: while creating Problem report we face "wt.org.WTGroup cannot be cast to wt.org.WTUser"

Hi Dhananjay chavan‌,

Seems like issue is with your customization.

As a starting point you can check your custom class "com.godrej.WorkflowHelper.java" and checkSetupParticipant method probably at line 387.

As Binesh Kumar‌ said WTGroup and passing it to WTUser group there in this method.

I hope you found it useful.

Regards,

Shirish
