The Seam events functionality in CVS is pretty useful. I prefer using the
annotations over events.xml but I find the annotations less flexible.
I would like to allow one method to observe multiple event types. How about
adding an @Observers annotation that works like @Roles? Here is an an example:
| @Observers({
| @Observer("somethingChanged"),
| @Observer("somethingElseChanged")
| })
| public void refresh() {
| ...
| }
|
This would make my code cleaner especially if I'm observing many event types.
Another suggestion is to add a priority hint to the @Observer annotation. This
could just be an arbitrary number (like a z-index) that allows Observer
instances to be sorted, allowing methods observing the same event type to be
fired in a sensible order. Here is an example:
| @Observer("somethingChanged", 0)
| public void meFirst() {
| ...
| }
|
| @Observer("somethingChanged", 100)
| public void meNext() {
| ...
| }
|
I hope this makes sense, I'll add this to JIRA if you think so.
