Boundary timer events on service tasks don't work in that way. Because Activiti will keep the transaction open for the full length of the Thread.sleep and the boundary timer event will not fire. Can you describe the use case for doing something like this?

Best regards,

No use case as such. I am just learning Activiti and trying out its features like boundary timer. From your comment, i learnt something which is not mentioned anywhere in the userguide. What other restrictions apply to boundary timer ??? Does it apply only for human task??? Thanks.

Is it a rule that both sides of the timer should be user tasks.???? I tried putting a service task when the boundary timer is triggered. but even that did not work..???
<blockcode>
<!– <serviceTask id="handleEscalation" name="Boundary timer task" activiti:class="services.ReverseStringsFieldInjectedBoundary"></serviceTask> –>
<userTask id="handleEscalation" name="Handle escalated issue"
activiti:candidateGroups="management">
<documentation>Escalation: issue was not fixed in time by first level
support</documentation>
</userTask>
</blockcode>

If "handleEscalation" task is a service task, it is not triggered. but it get trigered if it is a userTask…. Strange…!!!! 😞

Timers work on user tasks, receives tasks, etc. All the steps that are a 'wait state'

Service tasks cannot have timers. If you need the functionality, you will need to implement it yourself in the execute() method using JDK threads/timers, etc.

Putting a service after a timer works. Could you show your process + java code to see what you are doing?

Also, no need to use multiple question or exclamation marks, they work well with only one of them.
