Code:
@Override
public void persist(ActaDiferencia entity) {
try {
for (ActaDiferenciaValor av : entity.getValores()) {
getEntityManager().persist(av.getValor());
av.setEntidadId(av.getValor().getId());
}
getEntityManager().persist(entity);
getEntityManager().getTransaction().commit();
} catch (Exception ex) {
getEntityManager().getTransaction().rollback();
throw ex;
} finally {
closeSession();
}
}
When some Exception is throw, I have a problem with this line: getEntityManager().persist(av.getValor());
av.getValor() has an instance of Valorizable, the ID attribute of Valorizable are setted (Integer serial on a PostgreSQL DB) and the rollingback is not clearing the ID, so, if I try to persist again the object the POException "detached entity passed to persist" shows up.
How can I solve this?, I tried to set to NULL manually on a loop every Valorizable.id but the POE keep throwing
