Hi Vijay,

You should add adviseNodeSelected="#{myBean.adviseNodeSelected}" attribute to your rich:tree, and define corresponding method in the Bean class --

     /**
     * Return true if current node
     * must be selected in the tree.
     *
     * @param tree :UItree
     * @return boolean
     */
    public boolean adviseNodeSelected(UITree tree) {

       tree.getRowData();  // write business logic identifying if current node is the needed selected one, and return corresponding boolean....
       ........................................
    }
