" Is there any way to find whether task is persisted in DB before publishing message on queue?"

Yes, you need to CommandContextCloseListener and send the event when the transaction has been committed.
However, I'm pretty sure that CommandContextCloseListener is not available in 5.14 (any reason using such an old version?).
In that version, you'll probably have to use a Transaction listener (don't know the exact name anymore) where you wrap the logic in the post-commit callback.

Hi Joram,

Activiti has exposed Event as part of 5.15+. These are mentioned as part of activiti user guide under section 3.18 http://www.activiti.org/userguide/index.html#eventDispatcherEventTypes

can additional event listeners for events like TASK_CREATED, TASK_ASSIGNED help in identifying the creation of the usertask2 in above use case?

the events are different from what I answered above … that was about sending a CUSTOM event or data to something else.

But yes, the event listener can be used for this, but I think that a regular TaskListener is easier to use in this case.
