I think differently. For Alternatives, the Alternative with the highest
value is picked, while the others are ignored. There is no so much invoked
sequentially.
However, for interceptors/decorators/events, they are chained. Therefore,
I think events should follow the same fashion as interceptors/decorators,
which is to follow the ascending order.
Many thanks,
Emily

Hi all,
In a recent discussion with Martin, I realized that the use of @Priotiy
is not consistent in CDI 1.2:
- For Interceptor and decorator the lowest value in @Priority is first
(def in interceptor spec and 8.2.1)
- For Alternatives the Highest value in @Priroty is first (def in 5.2.2)
Since we have these different interpretation of @Priority value in the
spec , we may find more consistent to change the definition of event
ordering with the @Priority annotation.
Right now we have:
"Observers with smaller priority values are called first"
We may find more intuitive to change it to:
"Observers with higher priority values are called first"
I believe this one makes much more sense...
+1
It will remove the oxymoron effect of the sentence and align this
ordering on @Alternative way of using @Priorty.
Wdyt?
Antoine
