---------------------------------

             Summary: define behaviour of firing an event for an observer with transaction if the transaction is not open or marked rollback
                 Key: CDI-578
                 URL: https://issues.jboss.org/browse/CDI-578
             Project: CDI Specification Issues
          Issue Type: Clarification
    Affects Versions: 1.2.Final
            Reporter: Mark Struberg


The original problem description can be found at https://issues.apache.org/jira/browse/OWB-1111

If you have an observer 

{code}
public void clearCacheAfterTx(@Observes(during=TransactionPhase.AFTER_COMPLETION) ClearAfterTx payload) {...}
{code}

and you fire the event

{code}
clearCacheEvent.fire(new ClearCacheEvent());
{code}

In this case the behaviour when firing the event if the underlying transaction is already closed or rolled back is totally undefined. It might blow up or continue silently depending on the server.

The problem is that you cannot enlisten a Synchronisation at the tx anymore. 

I think we should define/clarify how it should behave in the various phases.

E.g. a during=AFTER_SUCCESS should NOT deliver the event immediately if the tx is already marked for rollback. But for AFTER_COMPLETION it might be perfectly fine.
At the end we need a matrix of the the event phases + possible Exceptions
