Some code. Problem in UPDATE query.

TypedQuery<List<Transport>> query = (TypedQuery<List<Transport>>) em.createQuery("SELECT t FROM Person p JOIN p.transports t WHERE p.personalCode = :code");

   query.setParameter("code", personalCode);
   List<List<Transport>> list = query.getResultList();
   List<Transport> temp = new Vector<Transport>();
   temp.add((Transport) attributeValue);
   list.add(temp);
   TypedQuery<Person> query2 = (TypedQuery<Person>) em.createQuery("UPDATE Person p SET p.transports = :list WHERE p.personalCode = :code", Person.class);
   query2.setParameter("list", list);
   query2.setParameter("code", personalCode);
   query2.executeUpdate();

This UPDATE query is invalid because JPQL UPDATE queries are limited to setting values not collections.

Following your report the exception in this case was fixed with a meaningful error message.
