Jboss seam tomahaw integration of jscookmenu
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 !!!
