Demetrio, don't use throws in methods exposed in Seam context session: jsf catch this exception and the enviroment will catch this, showing the page error wich you post here. You must throw exception like a "Blog Application", wich come with seam distribution; you must declare the Throwable class, like the example:

@ApplicationException(rollback=true)
  | @HttpError(errorCode=HttpServletResponse.SC_NOT_FOUND)
  | public class EntryNotFoundException extends Exception
  | {
  |    EntryNotFoundException(String id)
  |    {
  |       super("entry not found: " + id);
  |    }
  | }

and mark your method like


  | 	public void validaEmailNewsletter(FacesContext context, UIComponent toValidate, Object value)  throws EntryNotFoundException
  | 

And demark your right annotations to be rightly redirected. Ok?
