[ http://issues.apache.org/jira/browse/BEEHIVE-827?page=comments#action_12314256 ]
Mike Arnold commented on BEEHIVE-827: ------------------------------------- It appears the onCreate() method is no longer executed when returning from the action, so there appears to be no place to getPageInput() to retrieve the message and place into FacesContext. Do you have a recommendation as to how I can best retrieve the ActionOutput from inside my backing bean? Do I need to forward to a different faces view in order to execute getPageInput() from the onCreate() method of a new backing bean? > FacesMessages unavailable in JSF > -------------------------------- > > Key: BEEHIVE-827 > URL: http://issues.apache.org/jira/browse/BEEHIVE-827 > Project: Beehive > Type: Bug > Components: NetUI > Versions: v1m1 > Environment: Sun JSF-ri, Tomcat 5.0.28 > Reporter: Mike Arnold > Fix For: V1 > > I created a FacesBackingBean that raises an action in the controller.
