Enabling Hibernate versioning on TaskInstance for concurrent

[bdruth]

I need to provide optimistic concurrency control for TaskInstance objects in JBPM. I noticed that Comment, Token, ProcessInstance, and RuntimeAction use Hibernate versioning. Is there any reason I can't enable versioning on the TaskInstance mapping? Will the break anything in JBPM?

What's the reasoning behind not providing versioning on this by default? It would seem a logical choice, since TaskInstances are typically displayed in an Inbox type web-application, which typically needs Hibernate's definition of long running application transactions.

Cheers,
Brice

that should not break anything. just your schema will get updated. please file a jira issue for this. as i think that this is a bug and should be fixed in jbpm.

Sounds good, Tom. I'll do that. Thanks for the response!
