[seam-issues] [JBoss JIRA] Closed: (JBSEAM-374) Normalize the event model

Normalize the event model ------------------------- Key: JBSEAM-374 URL: https://jira.jboss.org/jira/browse/JBSEAM-374 Project: Seam Issue Type: Feature Request Components: Core Reporter: Gavin King Assignee: Pete Muir Currently some events can be handled by either an @Observer method, or a method binding in events.xml. Ideally we would like this to be true for ALL events, but for now our integration with JSF and jBPM is not quite that deep. Nevertheless, there are some things we could do to allow a more consistent model where everything can be handled by either a method binding or an annotated method: (1) Rebuild the page actions functionality on top of the Seam event bus - defining standard org.jboss.seam.page.<viewId> events that can be handled via @Observer("org.jboss.seam.page./myViewId.xhtml") (2) Introduce "outcome observers" for JSF: if I have <h:commandButton action="myOutcome"/>, allow us to handle it using @Observer("org.jboss.seam.outcome.myOutcome") (3) Ditto for jBPM: if I have <transition name="myTransition" ... />, allow us to handle it using @Observer("org.jboss.seam.transition.myTransition") (4) Finally, introduce annotations layered over @Observer: @RenderPage("/myViewId.xhtml"), @Outcome("myOutcome"), @Transition("myTransition")
