controlling rich:menu....no end in sight

[janson12]

i'm trying to get control over the rich:menu (since....i don't know when)with a HasMap storing the state of the menu groups and the selectedChild Attribute for the active menu item. Over a method called after a specific user interaction the menu has to collapse the currently opened group and expand another group + setting a specific item as active. While the HashMap is called collapsing seems to work but the menu won't expand even though the HasMap contains the correct values. Any ideas?

Hello,

This works well for me:

<rich:panelMenu>
 <rich:panelMenuGroup expanded="#{true}" label="Group 1">
 <rich:panelMenuItem label="Item 1" />
 <rich:panelMenuItem label="Item 2" />
 </rich:panelMenuGroup>
 <rich:panelMenuGroup expanded="#{true}" label="Group 2">
 <rich:panelMenuItem label="Item 1" />
 <rich:panelMenuItem label="Item 2" />
 </rich:panelMenuGroup>
 <rich:panelMenuGroup expanded="#{false}" label="Group 3">
 <rich:panelMenuItem label="Item 1" />
 <rich:panelMenuItem label="Item 2" />
 </rich:panelMenuGroup>
 </rich:panelMenu>

How do you reproduce the issue?

with rf 3.3.0 (btw. thanks a lot for that version!!) the menu groups behave as expected but the thing with the selected item still doesn't work. i create the menu dynamically and found out that neither

menu.setSelectedChild("#{NavigationMenu.selectedChild}");

nor

menu.setValueExpression("selectedChild", createValueExpression("#{NavigationMenu.selectedChild}", String.class));

seem to call/get/set the selectedChild value. here's the (simplified) code of the NavigationMenu bean holding the menu:

// Creating the menu

private void generateMenu ()
 {
 panelState = new HashMap<String, Boolean>();
 menu = new HtmlPanelMenu ();
 menu.setExpandSingle(true);
 menu.setId("mainMenu");
 menu.setMode("ajax");
 menu.setExpandMode("none");
 menu.setValueExpression("selectedChild", createValueExpression("#{NavigationMenu.selectedChild}", String.class));
 panelMenuGroup = generateSingleMenuGroup("header_01", render_header_01, "path1.jsp");
 generateSingleItem("item_01", render_item_01, "folder01/file01.jsp");
 menu.getChildren().add(panelMenuGroup);
/* do same for all groups and items */
}

// Creates the panelGroup, menu kept simple in this case

private HtmlPanelMenuGroup generateSingleMenuGroup (String labelName, boolean rendered, String path)
 {
 HtmlPanelMenuGroup tmpGroup = new HtmlPanelMenuGroup();
 tmpGroup.setLabel(rb.getString(labelName));
 tmpGroup.setRendered(rendered);
 tmpGroup.setId(labelName);
 tmpGroup.setName(labelName);
 tmpGroup.setValueExpression("value", createValueExpression("#{NavigationMenu.panelState['"+labelName+"']}",String.class));
 panelState.put(labelName, false);
 return tmpGroup;
 }

// Creates the menuItems

private void generateSingleItem(String labelName, boolean rendered, String path)
 {
 HtmlPanelMenuItem tmpPanelMenuItem = new HtmlPanelMenuItem();
 tmpPanelMenuItem.setReRender("ajaxArea");
 tmpPanelMenuItem.setIgnoreDupResponses(true);
 tmpPanelMenuItem.setLimitToList(false);
 tmpPanelMenuItem.setLabel(rb.getString(labelName));
 tmpPanelMenuItem.setId(labelName);
 tmpPanelMenuItem.setName(labelName);
 tmpPanelMenuItem.setRendered(rendered);
 UIParameter fParam = new UIParameter();
 fParam.setName(vh.getParamName());
 fParam.setValue(path);
 tmpPanelMenuItem.getChildren().add(fParam);
 tmpPanelMenuItem.setActionExpression(createActionExpression("#{ViewHandler.viewHandlerAction}"));
 panelMenuGroup.getChildren().add(tmpPanelMenuItem);
 }

// Switches to a specific item

public void switchToBackgroundprocesses(ActionEvent event)
 {
 //panelState = new HashMap<String, Boolean>();
 //THE GROUPS TO BE CLOSED
 this.panelState.put("header_01", false);
 this.panelState.put("header_02", false);
 /* and so on...*/

 // THE GROUPS TO BE OPENED
 this.panelState.put("header_03", true);

 // THE ITEM TO BE SHOWN IN ITALICS
 selectedChild = "item_04";
 }

// Should create Creates the value expression, e.g. for the selectedChild

private ValueExpression createValueExpression(String valueExpression, Class<?> cls)
 {
 FacesContext facesContext = FacesContext.getCurrentInstance();
 return facesContext.getApplication().getExpressionFactory().createValueExpression(
 facesContext.getELContext(), valueExpression, cls);
 }

selectedChild is called once at first load. so the value expression itself should be fine.
