Im having problems with HtmlTree and UITree. When i do "HtmlTree tree = HtmlTree() " or "UITree tree = UITree()" an exception is thrown.

I have included de richfaces 1.1 jars correctly but the exception says that cant found HmltTree.class (or UITree.class) . I think that this happens to me with every element in org.richfaces.components!!!!

Here is the backtrace:
