Mark Struberg commented on CDI-277:
-----------------------------------
There is another paragraph in the spec where this gets covered:
{quote}
10.2. Observer resolution
An event is delivered to an observer method if:
• The observer method belongs to an enabled bean.
{quote}
In my opinion the following must get clarified:
1.) This bullet clearly disables veto() beans from receiving Observers, right?
2.) @Alternative has no influence on Observers at all! They do not disable beans but only
affect the resolution process.
3.) A @Specializes class Y must be a subclass of another class X. If X defines an observer
method then this is also part of class Y and thus will get called.
4.) Any Reception.ALWAYS Observer method in X will NOT create a contextual instance of X
but _only_ of type Y (as X is not an enabled bean)
What I'm asking me is how one can disable a private observer method in it's
superclass or a static observer method at all ^^ Probably only via Extensions.
What if there are 2 Observer methods, both private and with the exact same name and
signature, but in different levels in the class hierarchy? Guess both will get triggered,
right?
Clarify inheritance behavior of observer methods
------------------------------------------------
Key: CDI-277
URL:
https://issues.jboss.org/browse/CDI-277
Project: CDI Specification Issues
Issue Type: Clarification
Reporter: Arne Limburg
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...
