Perhaps, but that would have to be added in 2.1 I think. You cannot expect a change to 1.2 spec at this point.

I'm fine with it being added to 2.1. I was searching for a standard way to do it in 1.2, but If that's not possible (as it seems to be the case), I understand it should be clarified on the next version.

Regarding your idea about an API or SPI to add bean defining annotations, I guess that would need to work *before* any extensions are called, no? So it would only work when the user is responsible of bootstraping the container? Just trying to understand before going further. Please let me know if this is not the place to ask for it. 

Thanks!

> I'm adding some annotations as stereotypes via an extension, with the purpose of converting into beans any classes annotated with them (JAX-RS resources in my specific case). What I'm facing is that classes with that annotations are still only discovered if they were to be discovered before. So when using discovery-mode="annotated", my JAX-RS resources are not passed to the @ProcessAnnotatedType event.
> WildFly automatically converts JAX-RS resources into @RequestScoped CDI beans, but looking at the code I saw it does that dealing directly with Weld APIs at server level, not on a portable manner at RESTEasy level.
> I haven't found any mention in the spec that my approach wouldn't work, but the TCK doesn't address this usecase, which makes me think it's not supported.
> Could you please clarify me the situation? Could this me changed on a future version?
> And the original email I sent:

> Hi,
>  
> I have a question about the behavior of the "BeforeBeanDiscovery#add*()" methods.
>  
> My usecase is the following: I'd want to convert all JAX-RS resources into CDI beans. That resources are all annotated with @Path. My understanding was that converting that annotation into a stereotype would make them eligible as bean types.
>  
> Since I can't modify that annotation, I just created an extension that observes the BeforeBeanDiscovery event and converts @Path into a stereotype associated with the @RequestScoped annotation. But it doesn't work, neither on Weld nor on OpenWebBeans. The class is not discovered on the next ProcessAnnotatedType event. 
>  
> I haven't found anything in the spec that explicitly says that a "runtime added" bean defining annotation makes clases eligible for discovery. But I think is makes sense.
>  
> Checking the TCK, test org.jboss.cdi.tck.tests.extensions.stereotype.StereotypeExtensionTest tests that the addition of the stereotype works, but doesn't cover my case of adding a stereotype to a non bean class.
>  
> Is this expected to work that way? Is a bug on the TCK and implementations? Any other way to achieve my goal?
