hi petemuir,
u're right i put h:messages into login page and i got an error like this :

  |  . value could not be converted to the expected type
  | 
i wrote my own converter as you told me 

  | @Transactional
  |     public Converter getApplicationConverter() {
  |         return new Converter() {
  |             
  |             @Transactional
  |             public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException {
  |                 if (arg2 == null) {
  |                     return null;
  |                 }
  |                 try {
  |                     return  ((EntityManager) Component.getInstance("entityManager")).find(Application.class, Integer.valueOf(arg2));
  |                 } catch (NumberFormatException e) {
  |                     throw new ConverterException("Cannot Find Selected Language", e);
  |                 }
  |             }
  |             
  |             @Transactional
  |             public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException {
  |                 if (arg2 instanceof Language) {
  |                     Application application = (Application) arg2;
  |                     return application.getName().toString();
  |                 } else {
  |                     return null;
  |                 }
  |             }
  |             
  |         };
  |     }
