Seam And ICEFaces menubar

davidalves Dec 19, 2006 8:30 PM

Hi I'm trying to build a menu using a Seam action as a backing bean for ICEFaces menuBar component.

I goes something like this:

MainMenuAction

@Stateless
@Name("mainMenuAction")
@Scope(ScopeType.SESSION)
public class MainMenuAction implements MainMenu {

 @In(required = true)
 User user;

 @Logger
 Log log;

 @Out
 public List<MenuItem> mainMenu;

 public String getMainMenu() {

 mainMenu = new ArrayList<MenuItem>();
 MenuItem mainClassifieds = new MenuItem();
 mainClassifieds.setIcon("xmlhttp/css/xp/css-images/menuitem.gif");
 mainClassifieds.setValue("Opt1");

 MenuItem searchClassified = new MenuItem();
 searchClassified.setIcon("xmlhttp/css/xp/css-images/menuitem.gif");
 searchClassified.setValue("Op2");

 MenuItem addClassified = new MenuItem();
 addClassified.setIcon("xmlhttp/css/xp/css-images/menuitem.gif");
 addClassified.setValue("Op3");

 mainClassifieds.getChildren().add(searchClassified);
 mainClassifieds.getChildren().add(addClassified);

 MenuItem myClassifieds = new MenuItem();
 myClassifieds.setIcon("xmlhttp/css/xp/css-images/menuitem.gif");
 myClassifieds.setValue("Opt4");

 mainMenu.add(mainClassifieds);
 mainMenu.add(myClassifieds);

 return null;
 }
}

mainMenuPanel.xhtml


<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:ice="http://www.icesoft.com/icefaces/component">
<body>
<h:form>
 <ice:menuBar orientation="vertical" >
 <ice:menuItems value="#{mainMenuAction.mainMenu}"/>
 </ice:menuBar>
</h:form>
</body>
</html>

I'm getting the following exception:

01:27:11,548 ERROR [D2DFaceletViewHandler] Problem in renderResponse: /main/mainMenuPanel.xhtml @9,63 value="#{mainMenuAction.getMainMenu}": Bean: org.jboss.seam.intercept.Proxy$$EnhancerByCGLIB$$1503199b, property: getMainMenu

I just started integrating ICEFaces with Seam so if this is an extremely n00b question I apologize in advance, butI've tryed a lot of variations.

Did you declare public String getMainMenu() in your MainMenu interface?

Any interface method is implicitly public, but yes I did explicitly declare the method as public.

(maybe I understood the quetion wrong)
Yes I declared an interface (marked it with the @Local annotation) and declared the method public String getMainMenu().

It pretty much looks like a class loading / caching issue to me. I am fighting with these kind of problems so often...

just a cheap advice : triple check all your class folders and clean everything before rebuild...

Hi, I've tryied a lot of combinations (method names etc) a still no luck.
I allways clean everithing before rebuild (my ant script does that when i select the deploy target)

So... any suggestions?

btw, there is an error in my xhtml page the EJB call is actually mainMenu.getMainMenu (that was only one of the other things I tryed)

Perhaps you should return something? And not null. Or you change the scope to APPLICATION?

Here's my menu bean:

@Stateless
@Name("sideNavigationMenu")
@Scope(ScopeType.APPLICATION)
public class SideNavigationMenu implements SideNavigation {
 @In
 private FacesContext facesContext;

 @In @Valid
 private User user;

 public List<MenuItem> getPanelNavigationItems() {
 List<MenuItem> menu = new ArrayList<MenuItem>();

 // generate menu

 return menu;
 }

And the JSF:

<ui:define name="sidebar">
 <ice:form>
 <ice:menuBar orientation="vertical">
 <ice:menuItems value="#{sideNavigationMenu.panelNavigationItems}" />
 </ice:menuBar>
 </ice:form>
</ui:define>

But I've another problem: As soon as I click on a menu item, an ICEfaces dialog pops up telling me the session is expired. What's that?

Thanks, It finally works!!!!!!!!!!!!!!!!!!!!!!! I had already tryed that but I always kept the property not only the getter.

I don't seam to have the "session expired" warning, the only thing I'm doing different is that I keep may menu in the SESSION scope.
