Martin Kouba commented on CDI-729:
----------------------------------
bq. To enable exceptionally and friends...
[~rmannibucau] I still don't get it. What does the {{CompletionStage}} param represent
and why is it needed? IMHO an observer should not care about what happened before/after
its notification.
Also note that async observers can be notified in parallel.
I can see a lot of misunderstanding in the comments which indicates that this topic is
difficult. But otherwise it's a good discussion. Keep going ;-).
Async event not CompletionStage friendly
----------------------------------------
Key: CDI-729
URL:
https://issues.jboss.org/browse/CDI-729
Project: CDI Specification Issues
Issue Type: Feature Request
Reporter: Romain Manni-Bucau
The goal of this ticket is to enable user to get injected the completion future instead
of the raw event and return another completion stage (generic type ignored) to enable the
"chain" to be synched.
Here is a sample:
1. fireAsync(persistEvent)
2. observer implementation does: return future.thenCompose(db::doAsyncPersist)
3. when the user gets back the result of the fireAsync the doAsyncPersist is completed.
