      I try to rerender a specific node by including it in a list which is passed to the render attribute of rich:tree in the tree node selection listener.

       

      render="#{bean.filterTreeRenderComponentIDs}"

       

      There is an old thread http://community.jboss.org/message/53393 about this. But if I try

       

      filterTreeRenderComponentIDs.add(tree.getRowKey());

       

      with a list of Object, I get

       

      java.lang.ClassCastException: org.richfaces.model.SequenceRowKey cannot be cast to java.lang.String

      If I try

       

      String id = currentSelectionKey.getSimpleKeys()[0].toString();

      filterTreeRenderComponentIDs.add("filterTree:" + id + ":tnCity");

      (I checked that the complete id is really in the page)

      I get

       

      null: java.lang.NullPointerException
