Hi all,

i'm trying to use rich:tree and rich:treeview as the example at this link: example_link

My question is when i try to load my page, i recive this error:

Exception during request processing:   Caused by javax.servlet.ServletException with message: "tried to access method org.richfaces.model.SwingTreeNodeImpl.setAllowUpdateParents(Z)V from class org.richfaces.model.SwingTreeNodeDataModelImpl"

It is possible to have a trivial example for the implementation of the rich:tree.

Thanks a lot!!!!
