    rich:tree implementation problem

    Hakan Moral Newbie

      hello i am trying to create a hierarchical tree of

       

      document types

                     -> document types2

                           -> document years

       

      and the types, types2 and years of the documents are taken from the tables in a db.

       

      i followed the samples given in the richfaces 3.3.3 final but i can see only the root element in the tree and tree does not respond to clicking for expanding. I debugged and can see the Treenodeimpl structure correctly but i could not be able to show it up in the view. the code is below:

       

      DocTreeManagerBean.java

      @Name("docTreeManager")
