The following two statements in the 1.0 spec apparently caused some confusion, section 10.2:
An event is delivered to an observer method if:
- The observer method has all the event qualifiers.
10.2.3:
Other, less specific, observers will also be notified of this event:
public void afterDocumentUpdated(@Observes @Updated Document doc) { ... }
public void afterDocumentEvent(@Observes Document doc) { ... }
So which one is it? If you fire @Updated Document, will both methods be called or not?
The confusion continues here:
https://issues.jboss.org/browse/WELD-767
https://issues.jboss.org/browse/WELD-454
http://docs.jboss.org/weld/reference/1.1.0.Final/en-US/html_single/#events
An observer method need not specify any event qualifiers—in this case it is interested in only unqualified events of a particular type.
It seems to me like WELD-767 was wrong and the documentation change needs to be reverted. Instead a solution to exclude
the less specific observer when a more specific event is fired would be:
public void afterDocumentEvent(@Observes @Default Document doc) { ... }
