[jbossseam-issues] [JBoss JIRA] Reopened: (JBSEAM-3641) Built-in async mechanism always returns null for Future.get()

Gabriel Goïc reopened JBSEAM-3641:
----------------------------------

>From 2.1 GA's documentation (chapter 22 p. 396):

return timer; //note that return value is completely ignored

If it was due to my method returning null (Future is the returned type), I would not have been able to do Future.get(), which returns null by the way.

As nothing is said about managing futures, I can only guess that it's just like managing timers, apart from configuring components.xml.

However, injecting an EJB3 timer or a Future as documentation suggests:

@In Timer timer; or @In Future timer;

only fails with this error:

org.jboss.seam.RequiredException with message: "In attribute requires non-null value: anyBean.timer"

so I can't return anything other than null to make the compiler happy. Either my application lacks something that is not in the documentation, or this return value is not that much ignored.

> When trying to use the built-in async mechanism, I'm unable to obtain the result of the asynchronous task using Future.get(). This always returns null.
> TimerServiceDispatcher seems to be installed , the asynchronous task runs perfectly. No error or misconfiguration has been seen even running in DEBUG or TRACE logging mode.
> Code, observations and bug are detailed here:
