Tomahawk t:panelNavigation2 execption...

[ved gunjan]

Hi Experts,

Im new the world of JSF and is presently trying the Apache MyFaces Tomahawk implementaion.

I'm trying to use the <t:panelNavigation2 > </t:panelNavigation2>



But it is giving me the this exception:



java.lang.IllegalStateException: Parent was not null, but this component not related
at javax.faces.component.UIComponentBase.eraseParent(UIComponentBase.java:437)
at javax.faces.component.UIComponentBase.access$500(UIComponentBase.java:56)

at org.apache.myfaces.custom.navmenu.htmlnavmenu.HtmlNavigationMenuRenderer.encodeEnd(HtmlNavigationMenuRenderer.java:99)
-----------------------------------------------------------------------------------------------------

This is my jsp code:

<t:panelNavigation2 id="nav1" layout="list" activeItemClass="selected" openItemClass="selected" >

<t:navigationMenuItems value="#{navigationMenu.panelNavigationItems}" />

</t:panelNavigation2>



The bean code is :

List menu = new ArrayList();
NavigationMenuItem products = new NavigationMenuItem("#{example_messages['panelnav_products']}", "#{navigationMenu.getAction}");
menu.add(products);
products.add(new NavigationMenuItem("#{example_messages['panelnav_serach']}", "#{navigationMenu.getAction}"));
products.add(new NavigationMenuItem("#{example_messages['panelnav_serach_acc']}", "#{navigationMenu.getAction}"));
products.add(new NavigationMenuItem("#{example_messages['panelnav_search_adv']}", "#{navigationMenu.getAction}"));
menu.add(new NavigationMenuItem("#{example_messages['panelnav_shop']}", "#{navigationMenu.getAction}"));
NavigationMenuItem corporateInfo = new NavigationMenuItem("#{example_messages['panelnav_corporate']}", "#{navigationMenu.getAction}");
menu.add(corporateInfo);
corporateInfo.add(new NavigationMenuItem("#{example_messages['panelnav_news']}", "#{navigationMenu.getAction}"));
corporateInfo.add(new NavigationMenuItem("#{example_messages['panelnav_investor']}", "#{navigationMenu.getAction}"));
menu.add(new NavigationMenuItem("#{example_messages['panelnav_contact']}", "#{navigationMenu.getAction}"));




This is same as the example.
