Error Message :
In cases where Events are submitted from a Workflow with parallel tasks, the Events are waiting indefinitely for the the parallel tasks to end.
The expected behavior is that when the evaluation of the Event is complete, and the condition check is positive, the next task is processed.
Root Cause: Events in state "WAITING_PARALLEL_TASKS" were not triggered if the running event has been cancelled. All events remain in a waiting state.
Update to a fix version listed below or a newer version if available.
Fix Status: Released
Automation Engine 12.1.1 - Available
Automation Engine 12.0.4 - Available
Automation Engine 11.2.7 - Available
