    PropertyNotFoundException with basic call to method

    Christian Zeidler Newbie

      Hello,

      I'm quite new to Seam and am encountering a problem that must be rather easy to solve ... I think, or hope...

      I'm trying to show/ hide elements on the navigation menu based on whether the user is logged in or not (as in the dvd-store example).

      Here is the code from the nav-menu:

      <f:subview rendered="#{login.test}">
       <li id="page_hidden"><s:link view="/hidden.xhtml" value="Hidden" propagation="none"/></li>
      </f:subview>
      


      Now for all simplicity, my LoginBean class contains the method test() wich simply returns true:
      public boolean test(){
       return true;
       }
      


      and the interface defines that method:
      @Local
      public interface Login {
      
       public String login();
       public String getUserName();
       public void setUserName(String username);
       public boolean test();
      }
      


      OK, so now here is the exception that I get when calling any page that uses tha menu:
      javax.faces.el.PropertyNotFoundException: /layout/nav.xhtml @9,45 rendered="#{login.test}": Bean: christian.navtest.Login$$EnhancerByCGLIB$$9bac42c3, property: test
