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.
