Instance of class Queue not found: Error and exception in a flow



A NullPointerException occurs when entering the problem flow after using a wait shape.

Error Messages

Problem flow abort due to currentFlow null 

Steps to Reproduce

1.Configure a parent flow to use a wait shape, that waits for its dependents to complete before progressing.  
2.Include an incomplete configuration that results in an error, which triggers the problem flow.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules, that results in the problem flow being called incorrectly.


This issue is scheduled to be resolved in new release Pega 7.1.9.  
Resolving the error resulting from the incomplete configuration avoids this behavior in the current version.
