ORM Problem

[assaf aharoni]

When i try to get the DeliveryHeader with all the data in the object depth, i get the DeliveryHeader with data but the perchaseOrderLinesList stays empty.
if i take the itemCrossReference out then the data retrieves fine.
Please Help !!!

method calling DAO in Action Class:

public String doList(){
		collection=deliveryDao.getAllDelayedDelivery();
		return "list";
	}

the DAO Code:

public Collection<DeliveryHeader> getAllDelayedDelivery() {
		Query query = entityManager.createQuery("from DeliveryHeader d Where d.deliveryHeaderPK.manufCompany.cmp_company_id=61");
		return query.getResultList();
	}
