debuggin:

                def plannedItems = cmmnRuntimeService.createPlanItemInstanceQuery().includeEnded()
                                                     .caseInstanceId(caseInstance.getId())
                                                     .orderByName().asc()
                                                     .list()

                println "Planned itm size: ${plannedItems.size()}"
                println "task count: ${taskService.createTaskQuery().list().size()}"
                plannedItems.each {
                    println "Before Sleep : name: ${it.name}, state: ${it.state}"
                }
                Thread.sleep(1000)
            }

Planned itm size: 3
task count: 1
Before Sleep : name: Human Task, state: available
Before Sleep : name: Human Task Alone, state: active
Before Sleep : name: Timer Event, state: available

After a while the timer completes but Human Task stays avaliabe.

Planned itm size: 3
task count: 1
Before Sleep : name: Human Task, state: available
Before Sleep : name: Human Task Alone, state: active
Before Sleep : name: Timer Event, state: completed

So looks like state changed on timer to completed. I was expecting Expire Task to be active. Why does it stay available?

Hi, you need to change the standardEvent of the planItemOnPart of the sentry to occur, like this:

<sentry id="sentry1">
        <planItemOnPart id="sentryOnPart1" sourceRef="planItem1">
          <standardEvent>occur</standardEvent>
        </planItemOnPart>
</sentry>

That was it. I really appreciate the help.

I can change it in the raw xml and it works. I cannot get it to change using the modeler. Start Trigger Transition Event choose occur, but xml still shows complete.

Never mind. You have to change the transition. :stuck_out_tongue_closed_eyes:
