[jboss-user] [JBoss Seam] - Seam injection fails

[beligum]

Hi all,

Can someone tell me what I'm doing wrong here?
I'm trying to inject the stateless RegisterAjaxAction class in my stateful RegisterAction class.
Here's the code:

  | @Stateful
  | @Scope(CONVERSATION)
  | @Name("register")
  | public class RegisterAction implements IRegister
  | { 
  |     @In(create=true) @Out(required=false)
  |     private Person newUser;
  |     @In(create=true) @Out(required=false)
  |     private LoginEntity newLoginEntity;
  |     
  |     @In(create=true)
  |     private RegisterAjaxAction registerAjax;
  |     
  |     @In
  |     private EntityManager em;
  |     
  |     @Logger
  |     private Log log;
  |     
  |     //-----CONSTRUCTORS-----
  |     public RegisterAction()
  |     {
  |     }
  | 
  |     //GETTERS, SETTERS, etc
  | 

and the injected class:


  | @Stateless
  | @Name("registerAjax")
  | public class RegisterAjaxAction implements IRegisterAjax, Serializable
  | {
  |     //-----CONSTANTS-----
  |     private static final long serialVersionUID = 2280962782361193463L;
  |     
  |     //-----VARIABLES-----
  |     @In(create=true)
  |     private Person newUser;
  |     @In(create=true)
  |     private LoginEntity newLoginEntity;
  |     
  |     private ResourceBundle msg = ResourceManager.getInstance().getGeneralMessages();
  |     private ResourceBundle regMsg = ResourceManager.getInstance().getRegisterMessages();
  |     
  |     @In private EntityManager em;
  |     
  |     //-----CONSTRUCTORS-----
  |     public RegisterAjaxAction()
  |     {
  |     }
  |     
  |     //STUFF...
  | 

I get this error message:
