Null pointer exception exporting from Explorer

neillamka — Sun, 17 Nov 2013 18:08:36 GMT

I'm new to Activiti so if I'm posting this question in the wrong place, please let me know.I am trying to create a flow using the Modeler on a Windows 7 X64 system using Activiti 5.14.The flow is a simple test one with a couple of steps and a boundary timer event trying to model a simple escalation

Have you set the timer duration?
Something in the line of: <code>
<boundaryEvent id="boundryTimerExpiresAfter14Days" attachedToRef="forApprovalTask" cancelActivity="true">
<timerEventDefinition>
<timeDuration>P14D</timeDuration>
</timerEventDefinition>
</boundaryEvent>
</code>

Yes, I set the timer duration to PT8H.

I'm only using the KIS BPM modeler but if I setup just the boundary timer and export I get the following.

<blockcode>
<boundaryEvent id="quoteEscalationTimer" attachedToRef="sid-211CCA37-0712-434A-9A94-4E698A486D7A" cancelActivity="true">
      <timerEventDefinition>
        <timeDuration>PT8H</timeDuration>
      </timerEventDefinition>
    </boundaryEvent>
</blockcode>

Adding the user task attached to that timer event then fails to export with the exception. I don't know if there is a way to look at something lower level since I can't export the XML.

In the designer, I captured what I added that causes the failure in case that helps. The image is here http://www.tastingmaster.com/downloads/Activiti_escalation_flow.png

Any news on this? I am seeing the same problem.
I cannot deploy or export any model with a timerBoundaryEvent

No, that is still a bug currently. I believe there is already a jira issue for this.

Hmmm. K.

I'm trying to create a reminder e-mail if the user doesn't complete their task in a timely manner.

Is there another BPMN pattern or workaround for this?
Any idea on fix date?

Im afraid you'll have to use the Designer or manually write the XML.
Reminder email is basically a timer boundary event on the user task (non-interrupting).

I took a look in Jira but did not see anything that looked like this issue. Do you happen to have the issue Id for the item you are referencing?

Thanks

Thanks for the response. But I must be misunderstanding your reply.

I cannot deploy any model with a timer BoundaryEvent no matter how I've created it (designer or hand XML) and if I understand your earlier reply from 12/19, this is a known bug.

Therefore, I was looking for a modeling work-around to do something (such as sending a reminder e-mail) if task not done in time.

Thanks,

The bug I mentioned was Activiti Modeler only.
You do can deploy models to the engine with a timer event (eg create with the Designer).

If I understand you correctly, you are not able to do that. Could you upload your process xml so we can try it ourself?

any update on when this will be fixed? It's a pretty nasty bug…

No, the modeler code base hasn't been touched for a while, nor is there a plan to work on it in the near future.

Is this problem solved in Activiti 5.16?
