Subject [jira] Closed: (MYFACES-261) MyFaces unable to find component referenced with 'for' tag
Date Wed, 01 Jun 2005 15:03:52 GMT
     [ http://issues.apache.org/jira/browse/MYFACES-261?page=all ]
     
Martin Marinschek closed MYFACES-261:
-------------------------------------

    Resolution: Fixed

Changed the exceptions thrown in this case to error log-messages - should be info enough to
the user that something is not working.

> [snip]
> (This is the "hello world" from _JavaServer Faces In Action_ example.) As the 'for' tag
refers to helloInput, a component that hasn't yet been defined, we get an exception and the
app won't deploy (below),
> Changing the order of the components, so the "helloInput" outputLabel is defined first
works, although we lose the ordering. Also, the notion of wrapping the two components as children
in a panelGroup does not appear to work, either.
> Behavior seen in 1.0.9 and nightly snapshot 20050530, running with WLS 8.1SP3 and Tomcat
5.0.18.
> javax.faces.FacesException: Could not render Message. Unable to find component 'helloInput'
(calling findComponent on component 'welcomeForm:errors')
