Hello Friends, I am new to myfaces tree2 component. I am trying to implement the an example given at
http://www.jroller.com/plainoldweblog/entry/use_tomahawk_tree2_and_ajax4jsf I am not able to expand the child node in the given example or any nodes added to child is not displayed. List childList = p_parentNode.getChildren(); TreeNode abc = new TreeNodeBase("folder", "MS Word Files", "302", false); List childList1 = abc.getChildren(); TreeNode abc1 = new TreeNodeBase("folder", "MS Word File 1", "3021", false); abc.getChildren().add(new TreeNodeBase("folder", "File 1", "3021", false)); abc.getChildren().add(new TreeNodeBase("folder", "File 2", "3022", false)); abc.getChildren().add(new TreeNodeBase("folder", "File 3", "3023", false)); childList1.add(abc1); childList.add(abc); Can somebody help me, I need to recursively expand the child node. I have given the source below. Thank you.
