Intermediate catch event triggers even when all my tasks are completed

Hello Users,I have a vaccation request workflow.In the flow there are multiple activities. The requirement is when the workflow is not completed with in some time frame i am supposed to do some things. So for that purpose i have used an intermediatecatch event which is started in a parallel gateway

You should, instead, add a sub-process around the whole process you have now. Add the timer-boundary-event on the boundary of this subprocess, having cancelActivity=true. When the timer fires, all active tasks in the subprocess will be cancelled, resulting in only one active path of execution in your process, being the outgoing path from the timer-event.

The reason why your process doesn't work is because the process can only finish when all parallel paths are finished. If you fork the execution into 2 paths: 1) Regular tasks and 2) timer, both regular tasks should be completed as well as the timer…

Thanks for replying. For the first part of your answer my timer works fine when the process is not completed as it gets triggered and that's what is expected do you mean that it can not be achieved using intermediatecatchevent.
For the second part i am using parallel gateway fork because i am need to have three different timers. Using time boundary event can i have three different timers.

If you have a fork/join, the process only ends of ALL parallel paths have ended. So if you have 4 paths (1 normal and 3 with an intermediate-timer event in it) the process will only end if all 4 of those flows are complete… So what I understand from your use case, this is not possible this way.

You can have 3 boundary-timers on the same sub-process, that's no problem.

Hello, I am posting my question in the same post, i have created three boundary-timers on the same sub process as you said.
My cancelActiviti is true in the last timer. I need to perform some operations so i am using execution listener for that inside the script task.
But once inside the listener the flow does not come out and it keeps on entering the listener infinitely. Now if i dont use any listener for the last timer it correctly ends the process. The only line in the listener: runtimeService.deleteProcessInstance(delegateExecution.getProcessInstanceId(), "Canceled");
Could you please tell what is wrong.
Here is the xml:
<boundaryEvent id="timer1" name="Timer1" attachedToRef="subProcess" cancelActivity="false">
          <timerEventDefinition>
              <timeDuration>PT80S</timeDuration>
          </timerEventDefinition>
      </boundaryEvent>
      <boundaryEvent id="timer2" name="Timer2" attachedToRef="subProcess" cancelActivity="false">
          <timerEventDefinition>
              <timeDuration>PT140S</timeDuration>
          </timerEventDefinition>
      </boundaryEvent>
      <boundaryEvent id="timer3" name="Timer3" attachedToRef="subProcess" cancelActivity="false">
          <timerEventDefinition>
              <timeDuration>PT180S</timeDuration>
          </timerEventDefinition>
      </boundaryEvent>
    <sequenceFlow id="flow1245" sourceRef="timer1" targetRef="scripttask1"/>
    <scriptTask id="scripttask1" name="Execute script" scriptFormat="JavaScript" activiti:autoStoreVariables="false">
          <extensionElements>
      <activiti:executionListener class="com.getinsured.hix.tkm.activiti.NotificationListener" event="end">
       </activiti:executionListener>
        </extensionElements>
          <script><![CDATA[
          println("**********I am inside script task1");

          ]]></script>
    </scriptTask>
    <sequenceFlow id="flow12456" sourceRef="timer2" targetRef="scripttask2"/>
    <scriptTask id="scripttask2" name="Execute script" scriptFormat="JavaScript" activiti:autoStoreVariables="false">
       <extensionElements>
      <activiti:executionListener class="com.getinsured.hix.tkm.activiti.NotificationListener" event="end">
       </activiti:executionListener>
        </extensionElements>
          <script><![CDATA[
          println("**********I am inside script task2");

          ]]></script>
    </scriptTask>
    <sequenceFlow id="flow12457" sourceRef="timer3" targetRef="scripttask3"/>
    <scriptTask id="scripttask3" name="Execute script" scriptFormat="JavaScript" activiti:autoStoreVariables="false">
     <extensionElements>
    <activiti:executionListener class="com.getinsured.hix.tkm.activiti.MyTaskListener" event="end">
       </activiti:executionListener>
     </extensionElements>
          <script><![CDATA[
          println("**********I am inside script task3");

          ]]></script>
    </scriptTask>
    <sequenceFlow id="flow124587" sourceRef="scripttask3" targetRef="theEndAll"/>
    <endEvent id="theEndAll" />

Instead to remove the listener, try to do something else in it, for example <code>System.err.println("Going to complete process instance" + delegateExecution.getProcessInstanceId() );</code> and monitor what happens.
