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 !!!
