Tree component in Subview causes java.lang.ClassCastExceptio
I have the following Tree in a subview which i include on other pages. The objective of the Tree is for navigation. I can get it to render, expand/collapse, slide off page etc .. but when I try to submit (non-ajax action) I get this exception .. any thoughts. I am able to get this pattern to work using other Tree components from other JSF libraries .. but need to use Rich Faces if possible.
java.lang.ClassCastException: org.ajax4jsf.component.UIDataAdaptor$DataState incompatible with [Ljava.lang.Object;
