Olá

Estou começando a trabalhar com JSF e estou tendo problemas na geração de menus dinâmicos.

Este é o erro que está ocorrendo:

WARNING: executePhase(RENDER_RESPONSE 6,com.sun.faces.context.FacesContextImpl@126c885) threw exception

Eu utilizo JSF + Tomahawk(jscookMenu) rodando pelo OC4J com a IDE JDeveloper.

abaixo segue minhas classes:

minha subview com o menu

<%@ page contentType="text/html;charset=windows-1252"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>

<f:subview id="menu">
    <h:form>
        <input type="hidden" name="jscook_action" id="jscook_action"/>
        <t:jscookMenu layout="hbr" theme="ThemeOffice" styleLocation="/css">
             <t:navigationMenuItem id="id_menu1" value="#{menu.navItems}"/>
        </t:jscookMenu>
    </h:form> 
</f:subview>

meu managedBean

package br.com.metaway.backedbean;

import org.apache.myfaces.custom.navmenu.NavigationMenuItem;

public class DynamicMenuTest {
    private NavigationMenuItem[] navItems;
    
    public DynamicMenuTest() {
        // children for item 2
        NavigationMenuItem[] subItems = new NavigationMenuItem[2];
        subItems[0] = new NavigationMenuItem("Subitem 2_1 Label","#{pessoaCad.actionListaTodos}");
        subItems[1] = new NavigationMenuItem("Subitem 2_2 Label","#{cidadeCad.actionTodos}");
        // item 2
        NavigationMenuItem itemWithChildren = new NavigationMenuItem("Item 2 Label", "");
        itemWithChildren.setNavigationMenuItems(subItems);
        // root items
        navItems = new NavigationMenuItem[3];
        navItems[0] = new NavigationMenuItem("Item 1 Label","");
        navItems[1] = itemWithChildren;
        navItems[2] = new NavigationMenuItem("Item 3 Label","");
    }

    public NavigationMenuItem[] getNavItems() {
        return navItems;
    }

    public void setNavItems(NavigationMenuItem[] navItems) {
        this.navItems = navItems;
    }
}

E erro estava na página jsp do subview (linha 10 d0 código).
O correto é:

1. <%@ page contentType="text/html;charset=windows-1252"%> 2. <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%> 3. <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%> 4. <%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%> 5. 6. <f:subview id="menu"> 7. <h:form> 8. <input type="hidden" name="jscook_action" id="jscook_action"/> 9. <t:jscookMenu layout="hbr" theme="ThemeOffice" styleLocation="/css"> 10. <t:navigationMenuItems value="#{menu.navItems}"/> 11. </t:jscookMenu> 12. </h:form> 13. </f:subview>
