[jboss-user] [JBoss Seam] - PropertyNotFoundException with basic call to method

[christian_zeidler]

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:
