[jbosstools-issues] [JBoss JIRA] (JBIDE-11867) Tooling for CDI Event identifies invalid observer

[Viacheslav Kabanovich (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-11867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12693083#comment-12693083 ] 

Viacheslav Kabanovich commented on JBIDE-11867:
-----------------------------------------------

It seems I implemented it the other way around. I followed the item
"10.2. Observer resolution: 
An event is delivered to an observer method if: 
...
The observer method has all the event qualifiers.
..."
I concluded from this, that if a fired event has a qualifier, then an observer needs to have it too, in order to receive the event; but that observer is free to have more qualifiers and they will not prevent the event from being delivered.

However, now reading in the beginning of chapter 10:
"An observer method will be notified of an event if the event object is assignable to the observed event type, and if all the observed event qualifiers are event qualifiers of the event.", I see that it is opposite to what I draw from 10.2.

Can it be that 10.2 contradicts to other statements, or is it my misunderstanding?
