[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=12598672#comment-12598672 ] 

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

One thing we could pretty easily do is to add a Float value representing an ordinal. But that really doesn't fit well to the general observer/observable pattern. What is your exact use case? From a quick think-through I don't see anything which cannot be done in a different way also.

> 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.
