Event listener with async service task does not update service

Hi,I am trying to use an event listener to update my UI when an unclaimed task becomes available in the workflow. While events are coming through, this does not seem to be reflected in the services when queried. This seems to be an issue that is more pertinent when using async tasks and the job exec

The state is only flushed at the end of the transaction. When you execute the query, the task is completed in memory, but only persisted to the db afterwards. Hence why you are seeing this behaviour.

Hi, thanks for your reply.

That's pretty much what I figured was going on. Is there something in the roadmap for an "end of transaction" event? This seems like a fairly common use case (update UI when a task state is changed), are we approaching this use case in an unexpected manner?

Thanks,

A colleague of mine created an issue: https://jira.codehaus.org/browse/ACT-2040.

Thanks.

I need to maintain reporting system of acitivity events, but they are not in DB yet while finding them in ActivitiEventListener

@hipodrom : can you expand on your use case?
If I'm understanding you correctly … one way to solve this would be to add the logic in a TransactionListener that acts on the 'committed' event.
