I have:
Events.instance().raiseTransactionSuccessEvent("doLongWorkAfterTxIsDone");
and
@Observer("doLongWorkAfterTxIsDone")
public void doWork() {
aSLSB.anAsyncMethod();
}
where anAsyncMethod() is a method marked @Aysnchronous. (I'd mark the observer
itself as @Asynchronous, but that gets ignored.) However, anAsyncMethod()
isn't called asynchronously, because TransactionCompletionEvent is an
AsynchronousEvent, and seam disallows spawning one asynchronous call from
another. But in my case, the CMT tx is committing (and the event is being
fired) upon return of a SFSB method that is executed within a web request, i.e.
very synchronously as far as the browser is concerned.
I'm not completely clear on the logic behind disallowing chained async calls,
so this may be misguided. But it seems to me that Asynchronous.execute()
should only set EXECUTING_ASYNCHRONOUS_CALL if it indeed sets up a new set of
contexts. That would allow the above code to work. Of course, it might break
something else :)
I have a workaround, which is to raise another asynchronous event from the
observer of the transactionComplete event, but that's rather convoluted.
Thanks for any input,
