[cdi-dev] [JBoss JIRA] Commented: (CDI-4) Need a way to provide ordering for Event observers (@Observes)

[Mark Struberg (JIRA)]

    [ https://issues.jboss.org/browse/CDI-4?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12600521#comment-12600521 ] 

Mark Struberg commented on CDI-4:
---------------------------------

huh, just realized that I could to the 2nd code block even more elegantly:

{code}
public void checkSecurity(@Observes MyEvent me, @Secured Event<MyEvent> securedEventSource) {
  checkSecurity();
  securedEventSource.fire(me);
}
{code}

The trick here is that any observer method can have additional injection points as parameters which will get resolved by the container automatically ...

> 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.
