Hi,
i've a class mapped with an EmbeddedId. My problem is when i do a simply hql select, it returns me a List with correct number of elements (size correct), bu all this object are "null". If i execute the sql (sql shown in the log), it works correctly.
Is moore clearly with code:

i deleted some functions, like hash, equals, etc.
then this is the code that executes de query:
Code:
//field=nudoss, vaue=someBigDecimal
public List<T> genericSearchList(String field, Object value) {
String hql = "from Zyco where " + field + "= :valor";
Query q = getEntityManager().createQuery(hql);
q.setParameter("valor", value);
List<T> result = null;
try {
result = q.getResultList();
} catch (javax.persistence.NoResultException nre) {
//we return null
}
return result;
}
then, the sql executes and, for example, it returns me a List with size 4 (correct), but all elements are null..
can anyone help me, please?
thanks in advance!
PD: i work with Oracle10g Database, and jta datasource
