Jason Porter commented on CDI-4:
--------------------------------
Maybe I'm coming at this from an odd angle, but why not allow them to register, via
the same service provider API, a Comparator<InjectionPoint> or
Comparator<ObserverMethod>? We could leave everything the way it is or create a
default one that just returns 0. This allows the users complete control over where each
observer falls in the set of observers, they don't need to add more XML, it's a
very simply, widely used pattern for ordering. Not sure why we're trying to reinvent
an ordering solution when one has already been provided by the language.
Need a way to provide ordering for Event observers (@Observes)

Key: CDI-4
URL:
https://issues.jboss.org/browse/CDI-4
Project: CDI Specification Issues
Issue Type: Feature Request
Components: Events, Portable Extensions
Affects Versions: 1.0
Environment: All
Reporter: Lincoln Baxter III
Assignee: Mike Brock
Fix For: TBD
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.
