Unable to go to resolved stage using Change Stage Utility

SA-32782

Summary



Unable to go to resolved stage using Change Stage utility with Pega 7.2.1.


Error Messages



trying to calculate the handle of a class whose instances may not be written to the database: Assign-: code: <none> SQLState: <none> Message: <none>


Steps to Reproduce



1. Create a case type which contains normal stages and alternative stages.
2. Include case wide supporting process.
3. Use Change Stage smart shape to move the case to alternative stage which is resolution stage.


Root Cause



User has accessed the newAssignPage in user's Activities and Data Transform rule after PRPC deleted the newAssignPage from Clipboard.

So when user access it, PRPC creates empty newAssignPage which does not have proper class.

Resolution



Before accessing newAssignPage, check whether it exists or not in clipboard.
