Examples of javax.faces.component.UIViewParameter

javax.faces.component.UIViewParameter
TODO: documentation on jsp and pld are not the same. It appear two params: maxlength and for, but no property getter and setter founded here. If maxlength is used, we can put something like this: JSFJspProperty(name = "maxlength", returnType = "java.lang.String") @author Simon Lessard (latest modification by $Author: struberg $) @version $Revision: 1188415 $ $Date: 2011-10-24 17:13:21 -0500 (Mon, 24 Oct 2011) $ @since 2.0
