Symptoms

We have a main workflow which has an IPC event to call the second workflow. It is the second workflow that is giving issues.The second workflow contains parallel activities ,all having client event and another activity after all these activities which has a preceeding rule to check that all parallel activities are completed before this activity is executed.There are 2 scenarios for this Workflow

1.When the instance takes a single path among all the parallel activities, the process completes successfully everytime.

2.When the instance takes more than 1 path among the parallel activities the workflow does not behave as expected.In this case all the events get completed everytime we run it but the workflow does not get completed everytime. Sometimes it gets completed and returns to the main workflow and at times it stays in the active state and does not return.
 

Diagnoses

The user is using 4.6.9. This issue is related to setting an activity to  complete the process.

 

Resolution 

We added a Placeholder event on the last activity of the sub process that doesn't proceed because it shows that it's still active even though it reached complete state, after adding placeholder event and testing the process 4 times, we didn't see any problem with it.
