problem with t:panelNavigation2

[Adam Mazurek]

Hi

I've got problem with <t anelNavigation2>. I have bean with code:

  
public CategoriesList() {

}

    public List<NavigationMenuItem> getCategoriesMenu() throws Exception {
    System.out.println("begin...");
    InitialContext ctx = new InitialContext();
    CategoryDAO dao = (CategoryDAO) ctx.lookup("shop/CategoryDAOBean/remote");
        List<NavigationMenuItem> menu = new ArrayList<NavigationMenuItem>();
       
        
        List<Category> mainCategories = dao.getMainCategories();
        for (Category cat:mainCategories) {
        NavigationMenuItem item = new NavigationMenuItem(cat.getName(),cat.getId()+"");
        
        List<Category> children = dao.getChildren(cat.getId());
        List childs = new ArrayList();
        for (Category c:children)
        item.add(new NavigationMenuItem(c.getName(),c.getId()+""));
        
        menu.add(item);
        } 
        return menu;
    }
 
    public List getCategoriesMenu2() throws Exception {
    System.out.println("begin...");
    InitialContext ctx = new InitialContext();
    CategoryDAO dao = (CategoryDAO) ctx.lookup("shop/CategoryDAOBean/remote");
        List<UINavigationMenuItem> menu = new ArrayList<UINavigationMenuItem>();
       
        List<Category> mainCategories = dao.getMainCategories();
        for (Category cat:mainCategories) {
        UINavigationMenuItem item = new UINavigationMenuItem();
        item.setId("_m"+cat.getId());
        item.setItemLabel(cat.getName());
        
        List<Category> children = dao.getChildren(cat.getId());
        for (Category c:children) {
        UINavigationMenuItem child = new UINavigationMenuItem();
        child.setId("_m"+c.getId());
            child.setItemLabel(c.getName());
        
        }
        
        menu.add(item);
        } 
        UISelectItems items = new UISelectItems();
        items.getChildren().addAll(menu);
        this.categoriesMenu2 = menu;
        return menu;
    }
 
  

when I write i jsp page:

  <t :-P	 anelNavigation2 id="nav1" layout="list" itemClass="mypage" activeItemClass="selected" openItemClass="selected" >
        <t:navigationMenuItems value="#{categories.categoriesMenu}" id="menu"/>
    </t :-P	 anelNavigation2>

when page is loading on my jboss console is:

    
22:38:34,453 INFO  [[/shop]] WARNING: Component _id192 just got an automatic id,
 because there was no id assigned yet. If this component was created dynamically
 (i.e. not by a JSP tag) you should assign it an explicit static id or assign it
 the id you get from the createUniqueId from the current UIViewRoot component ri
ght after creation!
 

The page is ok - there is the list of main categories as I wished but when I click on some item of menu I get exception:

javax.servlet.ServletException: Client-id : _id1 is duplicated in the faces tree.
javax.faces.webapp.FacesServlet.service(FacesServlet.java:121)
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)

when I try it with binding attribute:

<t :-P	 anelNavigation2 id="nav1" layout="list" itemClass="mypage" activeItemClass="selected" openItemClass="selected" >
        <t:navigationMenuItems binding="#{categories.categoriesMenu2}" id="menu"/>
    </t :-P	 anelNavigation2>

I get:

javax.faces.el.EvaluationException: Cannot set value for expression '#{categor
s.categoriesMenu2}' to a new value of type javax.faces.component.UISelectItems

When I used UISelectItems there were errors to.
Why are these errors. When You look in my bean code You there are setId explicitly. I have no idea what I do wrong...

I've solved the problem with unique id's. But the child elements aren't showed when I click on the menu element
