how to fire CDI event in stateless session bean @Asynchronous method

Hi,

I am trying to fire a CDI event in a session bean asynchronous method so that Vaadin views can update accordingly , however I getting an error and the stack trace is as below. It seems that the Vaadin session is missing when firing the event. Can anyone please tell me what have I done wrong?

@CDIUI("")
@Push(transport = Transport.LONG_POLLING)
public class SimpletestUI extends UI
{
  @Inject
  private MyView myView;
  @Inject
  private MyService service;

  @Override
  protected void init(VaadinRequest request)
  {
    final VerticalLayout layout = new VerticalLayout();
    layout.setMargin(true);
    setContent(layout);

    Button button = new Button("Click Mee");
    button.addClickListener(new Button.ClickListener()
    {
      public void buttonClick(ClickEvent event)
      {
        service.sendEvent();
      }
    });

    layout.addComponent(button);
    layout.addComponent(myView);
  }
}

@UIScoped
@CDIView
public class MyView extends VerticalLayout implements View
{
  private static final long serialVersionUID = 1L;
  public MyView()
  {
    addComponent(new Label("MyView"));
  }

  @Override
  public void enter(ViewChangeEvent event)
  {}

  public void eventObserver(@Observes final String msg)
  {
    UI.getCurrent().access(new Runnable()
    {
      @Override
      public void run()
      {
        addComponent(new Label(msg));
      }
    });
  }
} 

@Stateless
public class MyService implements Serializable
{
  private static final long serialVersionUID = 1L;
  @Inject
  private javax.enterprise.event.Event<String> event;

  @Asynchronous
  public void sendEvent()
  {
    try
    {
      Thread.sleep(1000L);
    }
    catch (InterruptedException e)
    {
      e.printStackTrace();
    }
    event.fire("Msg fired");
  }
}
