Hi
all Can one be so kind and explain me what I’m doing wrong. I must
not have understood something! Need help. What I would like is to recognize the menu node which has been pressed
by a user in my backing bean. In the backing bean I construct the menu dynamically as shown in the
example and get it displayed correctly in the .jsp. When I press a menu node the action function get called. So far OK. But in that function I cannot identify the menu node which has been
pressed, must say that all menu nodes call the same action function. The idea is to either grab the instance of the pressed menu node or to
find it in the value parameter, but no way .. neither I can identify and get
the node instance or have a value set in the value slot. I would appreciate if one could tell me how to identify the selected
node. Many thanks in advance. Roland Here a code snippet of the backing bean to show how I do it. private SelectItem selectedNode; public SelectItem getSelectedNode() { return
selectedNode; } public
void setSelectedNode(SelectItem sNode) { selectedNode
= sNode; } for (List<String> menuItems : navMenuList) {
String menuIndex = (String)menuItems.get(0); … menuNode = new NavigationMenuItem((String)menuItems.get(1),
"#{navTreeBean.actionSelectedNode}", null, false); menuNode.setDescription(menuIndex); // misuse ID menuNode.setValue("#{navTreeBean.selectedNode}"); mainMenuNode.add(childHeader); … Return menu; public String actionSelectedNode() {
ValueBinding xx = menuNode.getValueBinding("value");
System.out.println("the UIComponent found: " + xx); // OK found the UIComponent
#{navTreeBean.menu}
ArrayList<NavigationMenuItem> updateBinding =
(ArrayList<NavigationMenuItem>) xx.getValue(context);
for (NavigationMenuItem ni : updateBinding){
System.out.println("the NavigationMenuItem value: " + ni.getValue());
NavigationMenuItem node[] = ni.getNavigationMenuItems();
for (NavigationMenuItem nd : node)
System.out.println("the node:" + nd.getValue() + " id: " +
nd.getDescription());
}
return "page selected"; } Out put of above iteration: the NavigationMenuItem value: Users Maintenance the node:#{navTreeBean.selectedNode} id: 2 the node:#{navTreeBean.selectedNode} id: 3 the node:#{navTreeBean.selectedNode} id: 4 the node:#{navTreeBean.selectedNode} id: 5 the NavigationMenuItem value: Resources Maintenance the node:#{navTreeBean.selectedNode} id: 11 the node:#{navTreeBean.selectedNode} id: 12 the node:#{navTreeBean.selectedNode} id: 13 the node:#{navTreeBean.selectedNode} id: 14 the NavigationMenuItem value: Process controls the node:#{navTreeBean.selectedNode} id: 21 the node:#{navTreeBean.selectedNode} id: 22 the node:#{navTreeBean.selectedNode} id: 23 the NavigationMenuItem value: Inspection tools the node:#{navTreeBean.selectedNode} id: 31 the node:#{navTreeBean.selectedNode} id: 32 Roland Oertig IT architect, developer and consultant Klotenerstrasse 10 CH-8303 Bassersdorf
