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.
