Mark Struberg created CDI-229:

             Summary: introduce @OverridesAttribute for @StereoType
                 Key: CDI-229
                 URL: https://issues.jboss.org/browse/CDI-229
             Project: CDI Specification Issues
          Issue Type: Feature Request
          Components: Beans
    Affects Versions: 1.1.EDR1
            Reporter: Mark Struberg

We recently had a thread on the DeltaSpike list about using StereoTypes in real world applications: http://markmail.org/thread/uqozhsix2znwiebn

Imagine the following Stereotype for my Services (I spare out the standard

@StereoType @Secured @Transactional @ApplicationScoped public @interface @Service {}

The problem here is that there is no way to 'propagate' any rolesAllowed from
@Service to @Secured, etc.

What I'd like to have is something like ... public @interface @Service {

    String[] rolesAllowed();     TransactionAttributeType transactionType();


where the rolesAllowed() would get propagated to the @Secured meta-annotation
and transactionType() to the @Transactional 

Gerhard Petracek now pointed me to a cool feature which is used in JSR-303 BVAL: @OverridesAttribute

We should ping the BVAL EG for the details. There are quite a few little tricks and side effects to consider.

On the implementation side, we could e.g. pick the @StereoType annotation and automatically propagate those values to the AnnotatedType which get's passed to the Extensions
