Другие сущности, которые не могут быть брошены на javassist-util-proxy-proxy
Следующий поток [сущности не могут быть преобразованы в javassist.util.proxy.Proxy, у меня теперь есть ошибка на стороне сервера (tks thomas)не может столкнуться с реальной проблемой в моем приложении.

Ошибка на предприятии-производителе, но я работаю над Fiches.
Fiches связан отношением «многие к одному» со ссылкамиСписок литературы связан отношением «многие к одному» с продуктами.Продукция связана отношениями «многие-к-одному» с производителями.Может ли быть проблема с одним из моих прокси?
CEMFiches: (Строка 52 возвращает fichesDAO.readbyPK (fichesPK);)
public static Fiches fetch (String metier, String sitegeo, String cptdossier, Integer numligne) {
if (fichesDAO == null) {
HttpServletRequest request = RequestFactoryServlet.getThreadLocalRequest();
ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());

}
try {

return fichesDAO.readbyPK(fichesPK);
} catch (PersistanceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
IfichesDAO есть (используется @transactional)
public interface IFichesDAO {
@Transactional(readOnly=true)
public void save(Fiches fiches) throws PersistanceException;
public Fiches readbyPK(FichesPK fichesPK) throws PersistanceException;
}
FichesImpl является
@Transactional(readOnly=true)
public Fiches readbyPK(FichesPK fichesPK){
return (Fiches)getSessionFactory().getCurrentSession().get(Fiches.class, fichesPK);
}
FichesService:
public class FichesService

public FichesPK fetchPK(FichesPK id) { return CEMFiches.fetchPK(id); }
