Mark Struberg commented on CDI-277:
-----------------------------------

~jharting ok, let me rephrase: A non-activated @Alternative is _never_ target of a CDI event. The @Alternative must be enabled to get a CDI event. 

What I meant is that just having another 

@Alternative class B implements X 

for 

class A implements X 

will NOT disable any observer method in class A!

> Chapter 4.2 of the (1.0) spec misses a bullet point about inheritance of observer methods.
> Either
> - If X declares a non-static observer method x() then Y does inherit this method.
> or
> - If X declares a non-static observer method x() then Y does not inherit this method.
> (This behavior is different to what is defined in the Common Annotations for the Java Platform specification.)
> should be added.
> Don't know, what's right through...
