[rules-users] Drools 5.1.0.M2 - WorkItemNodeInstance --Listeners can't get hold of WorkItem object

[Vijay K Pandey]

Thanks Salaboy for looking into this.

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
Vijay

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?

Should I log this as a JIRA ticket.

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 18th April 2010 which I was earlier working on. Above is the only change in this class from the snapshot of 18th April and 5.1.0.M2
