> According to the JPA 1.0 spec - 4.6.4.1 Positional Parameters - p. 90:
> Note that the same parameter can be used more than once in the query string and that
the ordering of the use of parameters within the query string need not conform to the order
of the positional parameters.
> So, keeping it in mind, I can't explain why the following fails:
>    Query query = em.createQuery("SELECT DISTINCT o FROM Osoba o, IN(o.projekty) p WHERE
o.imie LIKE ?2 AND p.rodzajProjektu = ?1");
>    query.setParameter(1, RodzajProjektu.OTWARTY);
>    query.setParameter(2, "J%");
> with the following error:

2.0 BUILD 40 and I don't see the trouble there.
