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
