Summary

After upgrade to Pega 7.1.7, pzInternalCaseFlow errors occur in many of the work objects.

Error Messages

Unable to open instance using the given input : Assign - Internal - Work Class- Work Object # - PZINTERNALCASEFLOW

Steps to Reproduce

 

1. Create an activity that loops through pxFlow page.
2. Do obj-open-by-handle on every assignment found in the loop.
3. Call this activity from the post action of a flow action.

Root Cause

The pzInternalCaseFlow is a system flow which is created and used for stage based processing. The internal case flow is a virtual assignment, it has a pxFlow page, but the assignment is not actually written out to the database. Therefor, you are unable to successfully perform obj-open-by-handle.

Resolution

For these types of system flows, set pxSystemFlow to true. The best practice is to avoid trying to open or manipulate assignments where pxSystemFlow is set to true.
