    how to do dynamic binding on menu item in richfaces 4

    Savanna Johansen Newbie

      Hi! I wonder how we can do dynamic binding in richfaces 4. I have seen tutorials that work in previous versions of richfaces but not in this version.

       

       

      In my index.xhtml, i have definded a UIMenuItem like this:

      <rich:menuItem rendered="false"/>

       

       

      In the managed bean, I am doing these:

      UIMenuItem item = (UIMenuItem) ctx.getApplication().createComponent(ctx, UIMenuItem.COMPONENT_TYPE, "org.richfaces.MenuItemRenderer");

       

      Class[] params = {};

       

      MethodExpression action = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().createMethodExpression(ctx.getELContext(),"#{bean.action}",String.class, params);

       

      MethodExpression actionListener = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().createMethodExpression(ctx.getELContext(),"#{bean.action}",null, new Class[]{ActionEvent.class});

       

      item.setActionExpression(action);

      item.addActionListener(new MethodExpressionActionListener(actionListener));

       

       

      The action method that was wired with the component only does this since I am only testing if the dynamic binding works:

      public String getAction() {

          System.out.println("It worked!");  

          return null;

      }

       

       

       

      I tried binding it manually like this and it worked.

      <rich:menuItem rendered="false" binding="#{bean.action}"/>

       

       

       

      I just wonder how to do it dynamically... Any response would be appreciated.
