Steps to Reproduce

1. Launch a flow which first creates a WO and then calls updateStatus.
2. Observe error from updateStatus activity.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules. Calls within pzMapCases attempt to process the deferred list which has classes without correct interfaces to the deferred list.
