Hi,
I wrote the following code
Query query = em
.createQuery("SELECT node FROM NodeBO node WHERE node.parent = :aParent");
query.setParameter("aParent", parent);
Collection col = query.getResultList();
LOGGER.info("Number of children:" + col.size());It should return 1 object but it does not return it.
If I write it another way, the query work fine:
Query query = em
.createQuery("SELECT node FROM NodeBO node WHERE node.parent.id = :aParent");
query.setParameter("aParent", parent.getId());
Collection col = query.getResultList();
LOGGER.info("Number of children:" + col.size());Is it possible to give persitent object as parmater in a query ? What's wrong with the first way to writtte the query ?
J-C
