Take a look at this tests: https://github.com/Salaboy/Drools_jBPM5-Training-Examples/blob/master/jbp... https://github.com/Salaboy/Drools_jBPM5-Training-Examples/blob/master/jbp... More specifically the test called: reactiveProcessAndRulesTest () It uses the engine in reactive mode calling the fireUntilHalt() method. Hope it helps!

I was replying to the post of http://community.jboss.org/people/dalgwen dalgwen and http://community.jboss.org/people/afisboy Tom G regarding the org.drools.persistence.info.WorkItemInfo not being properly persisted. Curious fact : this error is triggerered in the second WorkItemHandler of my workflow, despite the fact that the first one use the same kind of code. When I debug, i see that : PersistenceContext context = ((PersistenceContextManager) env.get( EnvironmentName.PERSISTENCE_CONTEXT_MANAGER )).getCommandScopedPersistenceContext(); context.persist( workItemInfo );   ((WorkItemImpl) workItem).setId(workItemInfo.getId()); "workitemInfo" is ok, but its id is null, so the nullPointerException. I also debugged with the first WorkItem of my workflow, and then the id is ok after the context.persist(...) call. Don't know why it works the first time and not after. Basically I've got a WorkItemHandler which wraps a call to an external webservice. Once finished, this webservice asynchronously sends me a webservice callback and I then call the WorkItemManager.completeWorkItem in order to queue the next step in the workflow. I've persisted the WorkItemManager in a static variable in order to be able to access it from the client and the server but maybe that's the problem. Thanks for the help.

I see what you've done, good idea, I haven't thought about doing it this way. We'll give it a try. It's not as neat as having the asynchronous thread finishing the original workitem but there may be no way round it. I did think about creating my own persistence layer but that would be quite a lot of work so your workaround is a better solution.

I did one simple test (I took most of the code from your "emergency" exemple). With one JUnit execution you should be able to see the error. (maybe two or three executions because sometimes it crashes before, probably because of me messing things up) Here it is : http://dl.free.fr/getfile.pl?file=/r6iubu9C http://dl.free.fr/getfile.pl?file=/r6iubu9C (the link is available one month, you have to click on "Telechargez ce fichier", sorry it's a french provider ;-) ) For instance, here is the output of my Junit test: ----------------- Hibernate: insert into SessionInfo (id, lastModificationDate, rulesByteArray, startDate, OPTLOCK) values (null, ?, ?, ?, ?)
