Our application (using JBPM 5.1.0 final+ Hibernate+Spring), deployed on tomcat 6.0.26 gets an issue where sometimes when user completes a stage next stage does not become active.

We are unable to find out reason behind the same. So, to give a workaround we tried to rollback last operation performed by user.

We are taking below steps for the same :                   

1) Moving that Task into Ready state so that it can be claimed again

Update task set status = 'Ready', ActualOwner_id = null where id = <task-id>

2)We have audit tables for processinstanceinfo and WORKITEMINFO. So we also rollback last state into these tables.

So I am updating these three tables :

Task, processinstanceinfo, WORKITEMINFO

After this when we claim a task, JBPM completes it without any error but still it doesn't create the next stage.

Please clarify us with this issue and below set of queries.

Our application create workflow subprocess at every state. Just wanted to understand when does a new entry get added/removed from processinstanceinfo?

AM I missing any other table which needs to be updated
