Re: [eclipselink-users] Potential Bug in 2.1.1: values are written to wr

[Michael Simons <Michael.Simons@xxxxxxxxxxx>]

Hi Tom,

sorry for the delay - I had problems with my mailer.
The two classes and the persistence xml are attached.
Here's the code snippet that we're using. In the comment you see the clause that EL does not handle correctly:
	/**
	 * Retrieve unplanned orders.
	 * @param root -
	 */
	private void retrieveOrders (ISentinel root) {
		OrderManager omgr = managerFactory.getOrderManager(em, parent);
		TypedQuery<CustomerOrder> query = omgr.createCustomerOrderQuery (false, false, null, false, null);
		query.setHint(QueryHints.LEFT_FETCH, "o.schedule");
		query.setHint(QueryHints.LEFT_FETCH, "o.schedule.entries");
		query.setHint(QueryHints.FETCH, "o.deliveryAddress");
		query.setHint(QueryHints.FETCH, "o.deliveryAddress.location");
		query.setHint(QueryHints.FETCH, "o.deliveryAddress.customer");
		query.setHint(QueryHints.FETCH, "o.deliveryAddress.location.address");
		// When we set the following hint, the attributes of address are not mapped correctly anymore.
		//		query.setHint(QueryHints.LEFT_FETCH, "o.deliveryAddress.location.proposedAddress");
		query.setHint(QueryHints.LEFT_FETCH, "o.claim");
		query.setHint(QueryHints.LEFT_FETCH, "o.positions");
		for (CustomerOrder order : query.getResultList ()) {
			if (checkDomain(order) && (!parent.isOrdersInTime () || timefilter (order))) {
				if(order.getDeliveryAddress() == null)
					em.refresh(order);
				root.addOrder (order);
			}
		}
	}

I'll try to reproduce the failure in a less complicated query, because I guess the problem is that Location references Address two times. But maybe you're already able to detect the problem.

Kind Regards, Michael

Michael,

   Can you please post all the information related to how these items are 
mapped?  (classes with annotations, relevant xml files)

   Also, can you please post the code snippet you are using to read the objects.
