Hi everybody, since last Sunday I'm trying to get RichFaces Tree component working.. unfortunately inefficaciously-:)
The best I've got is a ClassCastException:) I was following example from http://livedemo.exadel.com/richfaces-demo/richfaces/tree.jsf?s=classic Only thing I added is: @Name("library") @Scope(ScopeType.SESSION) to annotate Library class as a Seam Bean, all the others pieces of code are absolutely identical with given example. Maybe it's important to say that I've used Facelets too. JBoss server log has only following exception: 11:39:18,421 ERROR [STDERR] Sep 4, 2007 11:39:18 AM com.sun.facelets.FaceletViewHandler handleRenderException SEVERE: Error Rendering View[/main.xhtml]
