Subject [jira] Created: (BEEHIVE-827) FacesMessages unavailable in JSF
Date Fri, 17 Jun 2005 21:44:16 GMT
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


I created a FacesBackingBean that raises an action in the controller.  The action returns
a Forward sending the request back to the JSF.  The forward generates an ActionOutput of a
simple String message.  In the onCreate() method of the FacesBackingBean I called getPageInput()
to retrieve the ActionOutput.  I then cast the output as a string and pass it to a new FacesMessage
which is passed to FacesContext.getInstance().addMessage().  In the JSF, the message is not
displayed using the <h:messages/> tag.


If I add the new FacesMessage to FacesContext in an event handler that does not raise an action,
the message is displayed as expected.


If I add the new FacesMessage to FacesContext in onCreate() without going through an action,
the statement throws a NPE.

@Override
protected void onCreate() throws Exception {
     FacesContext.getCurrentInstance().addMessage("foo", new FacesMessage("bar"));
}
