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"));
}
Stack Trace:
java.lang.NullPointerException
