start task with signal

micharg — Mon, 20 Jan 2014 17:27:05 GMT

Hello,I have to tasks that are active at the same time, lets call them R and O. R is required and O is optional.How can I model this? I want when R is finished also O be finished. If O is finished R should be finishedalso.I don't want to finish task O manually after I finish R. I have tried messages

Hi Mike.

If finished = completed
one option could be to complete tasks automatically by service task after the user task. (TaskService API call)

May be you can find better solution.

Hello Martin,

Thanks for your recommendation. I will try this. By the way signals should be caught? I was thinking an Signal Intermediate Throw Event
and catching it (with cancel activity = true) but the signal is never caught (I use a signal boundary event)

Regards,
Mike

In that case you should have a look on org.activiti.engine.test.bpmn.event.signal.SignalEventTest#testSignalCatchBoundary in the activiti sources.


 <signal id="alertSignal" name="alert" />

 <process id="catchSignal">

  <startEvent id="start" />

  <sequenceFlow sourceRef="start" targetRef="task" />

  <userTask id="task" activiti:assignee="kermit" />   
  
  <boundaryEvent id="boundary" attachedToRef="task" cancelActivity="true">       
          <signalEventDefinition signalRef="alertSignal"/>
       </boundaryEvent>

  <sequenceFlow sourceRef="task" targetRef="end" />
  <sequenceFlow sourceRef="boundary" targetRef="end" />

  <endEvent id="end" />

 </process>
