Thanks for a quick response. I added the Transaction Manager piece of code but the problem still persists. Also it uses the attached persistence.xml file which is placed under META-INF directory that has the correct transaction manager look up class.

Thanks

I've just take a quick look to your file and I notice (without running it) that you didn't set the TransactionManager property to your Environment:

env.set( EnvironmentName.TRANSACTION_MANAGER,

         TransactionManagerServices.getTransactionManager() );

You also need to have the reference to bitronix inside your persistence.xml file:

<property name="hibernate.transaction.manager_lookup_class"

                value="org.hibernate.transaction.BTMTransactionManagerLookup"/>

Can you try this and let me know if it fix your problem?
Greetings

Here is the Junit Test case(java file attached) I created for this problem.

Line # 129 fails.

Please do let me know if I am doing something wrong or the fix has some issues or maybe there is some other way out to get hold of the “WorkItem” object in the process event listener.

Thanks

I guess this problem was due to a fix done in WorkItemNodeInstance? Is this the correct behavior? If yes how do we get hold of “WorkItem” instance in the attached listeners?

Any one on this issue? Any Drools Flow expert?

Appreciate your time for taking a look at it.

Should I log this as a JIRA ticket.

Subject: Drools 5.1.0.M2 - WorkItemNodeInstance -- Listeners can't get hold of WorkItem object

Hi,

There is a change done in Drools 5.1.0.M2 - org.drools.workflow.instance.node.WorkItemNodeInstance class in the method

public void triggerCompleted(WorkItem workItem) at line 196 which is setting the workItemId as -1

this.workItemId = -1;

Due to the above change the listeners which are attached to the “complete” event of the work item – such as the method below

public void beforeNodeLeft(ProcessNodeLeftEvent event) are not able to get hold of the associated workitem object as it returns null.

Is there any specific reason that workItemId is set to -1 even before the associated listeners get triggered or is this a bug?

If it was an intended change then how do I get hold of the “WorkItem” object in the attached listeners.

Thanks

Vijay

p.s This change was not there in the snapshot of 18^th April 2010 which I was earlier working on. Above is the only change in this class from the snapshot of 18^th April and 5.1.0.M2
