Alexandr Sokolov commented on CDI-696:
--------------------------------------

John, if MDB would no be actually managed bean, I would not be able to inject beans in to it. And I'd have to think about life cycle of this bean. It seems that some functionality works with MDB, like with usual managed beans. But exact decorators - no.

> Guys, I'm using Wildfly 8.2.1.Final
> Here is MDB bean:
> {code:java}
> @MessageDriven(activationConfig = {
>         @ActivationConfigProperty(propertyName = "destinationLookup",
>                 propertyValue = "topic/dse"),
>         @ActivationConfigProperty(propertyName = "destinationType",
>                 propertyValue = "javax.jms.Topic")
> })
> public class JobChangedSubscriber implements MessageListener {
> ...
>     @Override
>     public void onMessage(final Message message) {
> ...
>     }
> }
> {code}
> And decorator:
> {code:java}
> @Decorator
> public class RetroplannerSubscriber implements MessageListener {
>     @Inject
>     @Delegate
>     @Any
>     JobChangedSubscriber jobChangedSubscriber;
>     @Override
>     public void onMessage(Message message) {
>         jobChangedSubscriber.onMessage(message);
>         //custom code
>     }
> }
> {code}
> During deployment, all mistakes about decorator definition are shown. They were fixed. I was sure it would work. But now, only JobChangedSubscriber.onMessage() is invoked.
> As a user I want to decorate MDB as an usual CDI bean. What am I doing wrong?
