Thomas Andraschko commented on CDI-407:

Yep, thats what i expected.
In this case, is there any reason to still install/configure A as active bean?
As there is no qualifier or stereotype available, it would be possible to automatically install B as @Named("a") without explicity giving it a name.
Or do i miss something here?

@Named("a") is a workaround but feels "ugly" and you always have to synchronize the names.

> It's actually a must-have for product development and a common case.
> We would like to have multiple implementations in our core and just activate them via alternative.
> I talked with struberg and its currently not defined in the specs.
> e.g.
> @Named public class A
> @Named @Alternative public class B extends A
> What should acutally happen if B is activated via beans.xml?
> IMO B should be available in EL via "a" and "b".
