[jboss-user] [JBoss Seam] - HELP! get exception when add @Restrict(

[yadong]

When I add @Restrict("#(identity.loggedIn)") to an Action (session bean) in class level, it throws exception when it is called.

@Stateful
@Scope(ScopeType.SESSION)
@Name("testAction")
@Restrict("#(identity.loggedIn)")
public class TestAction implements Testing {
 ...
    public String getName(){
          return name;
   }
}

in JSF page:

<h:inputText id="test" value="#{testAction.name}" />

if I remove the @Restrict("#(identity.loggedIn)") , or replace it by:
@Restrict("#{s:hasRole('admin')}") 
it is running well without execption
