Boundary Event on SubProcess Not Firing

Hi,Please provide answers for below queries -1. I have a sub process named "Document Approval Sub Process" with activities (Start -> Approve LC Docs User Task -> Collect Approval Status -> End). Timer event is attached to this sub process and the same is not getting fired. Please let me kno

Hi,

Is it possible not to cancel first sub process

yes


<boundaryEvent id="boundaryTimer" cancelActivity="true"….

and both sub process remain active in case timer reached specified time?

In that case you do not cancel Activity (false)

Also if any user (using user task from first sub process) or any user (using user task from escalation sub process) approves or rejects, the process can be completed successfully.

I would say to use messages (or signals), after the task complete to notify subprocess about the execution state.

Also not able to design the process flow using Activiti Explorer…

I can not answer.

Regards
Martin

Hi Martin,

Timer event is not getting fired for escalation.bpmn20.xml process. Could you please help me out on this by letting me know what is wrong?

I would say to use messages (or signals), after the task complete to notify subprocess about the execution state.
[Puja] Please help me out with an example.

Thanks,

Hi,

The timer boundary event on a multi instance sub process is not firing. Is this an issue with Activiti? Please help me out on this. The config file and bpm process are attached above. What is the alternative to achieve the same?

Thanks,
Puja

Hi Puja,

I have found similar jUnit test in activiti project

    List<Task> tasks = taskService.createTaskQuery().list();
    assertEquals(6, tasks.size());
    
    // Complete two tasks
    taskService.complete(tasks.get(0).getId());
    taskService.complete(tasks.get(1).getId());
    
    // Fire timer
    Job timer = managementService.createJobQuery().singleResult();
    managementService.executeJob(timer.getId());
    
    Task taskAfterTimer = taskService.createTaskQuery().singleResult();
    assertEquals("taskAfterTimer", taskAfterTimer.getTaskDefinitionKey());
    taskService.complete(taskAfterTimer.getId());
    
    assertProcessEnded(procId);
  }

Thanks Martin.

The JUnit works fine.

But if I deploy this process and start the same. After specified time the timer is not getting fired on its own. Please help me out on the same.

Did you set processEngineConfiguration's jobExecutorActivate property to true?


    <property name="jobExecutorActivate" value="true" />

Hi,

Yes, I have set processEngineConfiguration's jobExecutorActivate property to true.

could you create your own jUnit test for it please?

Hi Martin,

I have performed below JUnit -

@Deployment
public void testParallelSubProcessWithTimer() {
    String procId = runtimeService.startProcessInstanceByKey("miParallelSubprocessWithTimer").getId();
    List<Task> tasks = taskService.createTaskQuery().list();
    assertEquals(6, tasks.size());

    // Complete two tasks
    taskService.complete(tasks.get(0).getId());
    taskService.complete(tasks.get(1).getId());

}

After that -

1. I waited for 1 hour.
2. Went and checked ACT_RU_TASK table in DB. This table still had remaining 4 tasks. These were not terminated.
3. ACT_RU_JOB table still had the record.

In short, the job entry didn't trigger the timer end event (to terminate remaining 4 tasks and to create the task after timer).

Puja

Hi Puja,

Job executor did not fire job execution. The question is why.

Was process engine running during the waiting hour?
Did you try original MultiInstanceTest#testParallelSubProcessWithTimer (Did the test work)?
If you create (http://forums.activiti.org/content/sticky-how-write-unit-test) project it would make things much easier.

Hi Martin,

How to ensure the process engine is keep running?

I just run the JUnit and waited for 1 hour as specified above.

Puja

Hi Puja,

Usually there is no need to wait an hour to test the event.
Process engine is driven by clock interface implementation (e.g. DefaultClockImpl). You can set time:


  Calendar tomorrow = Calendar.getInstance();
  tomorrow.add(Calendar.DAY_OF_YEAR, 1);
  processEngineConfiguration.getClock().setCurrentTime(tomorrow.getTime());
  waitForJobExecutorToProcessAllJobs(2000, 100);

Hi Martin,

We have used Activiti in our web application. We start approval process when user clicks on submit button on user interface and BPM Process (designed for approval) creates user task(s). If user (i.e. Approver in our case) doesn't act on task, we want to escalate it to another group of users. The web app remained up and running. Process Engine also up as the bean got created through spring application context on application start up. But we found that timer event didn't get fired on its own after the specified time. That's why above conversation and number of questions.

Understood that Process engine is driven by clock interface implementation (e.g. DefaultClockImpl).

Whether we need to explicitly set time as specified above (from our some piece of code) in real scenario? I was under an assumption that timer event should get fired on its own after specified time. Please suggest and help me out in resolving this.

Thanks,
Puja

Hi Puja,

when I want to help you, I need to reproduce the issue. I think it is not possible to install whole environment with web app…. on my local machine. That's why I preferred jUnit tests (and all my comments were related to the jUnit tests).
Questions:
Could you reproduce the issue in failing jUnit test? (http://forums.activiti.org/content/sticky-how-write-unit-test)
Could you attach this jUnit test (as zip or on the github)?

Martin
