------------------------------------------

Hello Marek,
thanks for your fast reply. In this moment I'm investigating about this problem. I've try this code in a ActionHandler Class, but until now I not have the roolback work in both session ( session from seam and session from jbpm )...

{code:title=TestActionHandler.java|borderStyle=solid}
public class TestActionHandler implements ActionHandler {
	
	private static final long serialVersionUID = 1L;

	public void execute(ExecutionContext executionContext) throws Exception {
				
		Log log = Logging.getLog(ControlloDocumento.class);
				
		Session sessionjbpm = executionContext.getJbpmContext().getSession();
		Session session = (Session)Component.getInstance("session");
		
		log.info("Session take from jbpm   : #0", sessionjbpm.hashCode());
		log.info("Sessione take from seam: #0", session.hashCode());
		
		Document doc = (Document)session.get(Document.class, 23l);
		doc.setMessage("Write some data for test rollback... " );
		
		throw new RuntimeException("Throw some exception for test"); 
		
		// After the previous code the "message" property of doc entity save the modify and not do the rollback !!!		
	}
}
{code}

Some idea to fix ?
Can help me? If you have time can contact you directly... I'm frustrated and shot down :(

> I have made a simple change to the ShipAction.java class in the dvdstore example that ships with Seam. Here is the change
> //@EndTask
> public String ship() {
>     order.ship(track);
>     TaskInstance ti = ManagedJbpmContext.instance().getTaskInstance(taskInstance.getId());
>     taskInstance.end();
>     if(true) throw new RuntimeException("TESTING");
>     return "admin";
> }
> I commented out the end task annotation and I am ending the task via the TaskInstance API. When I throw the Runtime exception the changes to the ORDERS entity bean (i.e. updating the tracking number) rolls back. The problem is that the task instance change (i.e. ending the task) does not rollback. It appears that jBPM is flushing its changes in another db transaction.  This seems like a bug since I would expect the ending of my task to also rollback.  This seems like the desired behavior.
