Antonio Goncalves commented on CDI-4:

And now that we have {{@Priority}}, can't we just use it ?

public class MyBean
	public void myFirstObserverInPriority(@Observes @Priority(1000) MyEvent event) { ... }

public class MyBean
	public void mySecondObserverInPriority(@Observes @Priority(42) MyEvent event) { ... }

> There needs to be a way to specify some kind of ordering for Event observers. 
> Understandably, this is somewhat counter-intuitive to the general concept of observing an event, but there is going to be need for this in an upcoming JBoss project. While it can be done manually, it might be nice to have a built-in API.
