    Jboss seam tomahaw integration of jscookmenu

    sebastien larchet Newbie

      hi everybody

      I'm currently facing a strange pb between Tomahawk and Jboss Seam.
      It looks like NavigationMenuItem[] object returned by my Stateless Bean lose some cast information's when it's handled by NaviagtionMenuUtils class of tomahawk package.

      My test configuration is :
      a superMenu.jsp contains a JsCookMenu tag that dynamically get menu items from a stateless bean.

      my software cfg:

      Jboss is 4.04.GA
      Seam is 1.0.1
      MyFaces 1.1.3
      Tomahawk 1.1.3
      Linus RH Enterpise 4.XX
      JDK Sun 1.5.0_05-b05

      my Stateless Bean source taht returns the array of NavigationMenuItem:

      import static org.jboss.seam.ScopeType.STATELESS;
      import java.io.Serializable;
      import org.jboss.seam.annotations.*;
      import org.jboss.seam.log.Log;
      
      import org.apache.myfaces.custom.navmenu.NavigationMenuItem;
      
      @Name("mainMenu")
      @Scope(STATELESS)
      public class MainMenu implements Serializable
      {
       @Logger
       private Log log;
      
       public MainMenu()
       {
       }
      
       public NavigationMenuItem[] getNavItems() {
       NavigationMenuItem[] navItems=new NavigationMenuItem[2];
       navItems[0]=new NavigationMenuItem("Item 1 Label","action1");
       navItems[1]=new NavigationMenuItem("Item 3 Label","action3");
       System.out.println("produced class name="+navItems.getClass().getName());
       return navItems;
       }
      }
      


      my jsp source wich invoke mainMenu.navItems

      part of org.apache.myfaces.custom.navmenu.NaviagtionMenuUtils (addNavigationMenuItems method) class that I decorated with a System.out.println in order to make simple checking and follow progress of objects in Eclipse debugger.

      public static void addNavigationMenuItems(UISelectItems child, List list)
       {
       Object value = child.getValue();
       System.out.println("returned class name="+value.getClass().getName());
      
       if (value instanceof NavigationMenuItem)
       {
       list.add(value);
       }
       else if (value instanceof NavigationMenuItem[])
       {
       for (int i = 0; i < ((NavigationMenuItem[])value).length; i++)
       {
       list.add(((NavigationMenuItem[])value));
       }
       }
       else if (value instanceof Collection)
       {
       for (Iterator it = ((Collection)value).iterator(); it.hasNext();)
       {
       Object item = it.next();
       if (!(item instanceof NavigationMenuItem))
       {
       FacesContext facesContext = FacesContext.getCurrentInstance();
       throw new IllegalArgumentException("Collection referenced by UINavigationMenuItems with id " + child.getClientId(facesContext) + " does not contain Objects of type NavigationMenuItem");
       }
       list.add(item);
       }
       }
       else
       {
       FacesContext facesContext = FacesContext.getCurrentInstance();
       throw new IllegalArgumentException("Value binding of UINavigationMenuItems with id " + child.getClientId(facesContext) + " does not reference an Object of type NavigationMenuItem, NavigationMenuItem[], Collection or Map");
       }
       }

      I can produce the same kind of error If return a List of NavigationMenuItem instead of an array. In this case, the List instance is properly recognized but items returned by iteration aren't detected as NavigationMenuItem.

      I 'm now stucked on this pb since a week.
      I haven't seen any pb of this kind posted here, I hope that's only a configuration pb from me.


      please help !!!
