[cdi-dev] [JBoss JIRA] (CDI-696) Decorator for MDB is not used

[John Ament (JIRA)]

    [ https://issues.jboss.org/browse/CDI-696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13375985#comment-13375985 ] 

John Ament commented on CDI-696:
--------------------------------

Most specs are pretty ambiguous in this area, however the root of the problem is that most of these EE objects are not actually managed beans. If you look at message listeners, servlets, filters, they all support injection, but themselves are not managed by CDI as a runtime.  The containers will delegate down to CDI to provide injection support into those classes.

> 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?
