[Hibernate-JIRA] Created: (HHH-2920) Polymorphic association with explicit table_per_class strategy: properties of subclass are not retrieved by queries.
by Andrea Silva (JIRA)
Polymorphic association with explicit table_per_class strategy: properties of subclass are not retrieved by queries.
--------------------------------------------------------------------------------------------------------------------
Key: HHH-2920
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2920
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.5
Environment: Java 1.5 - Hypersonic DB - Standalone application
Reporter: Andrea Silva
Priority: Minor
Attachments: src.zip
Item class has a one-to-many association to Bid. Bid class has a subclass called CashBid (meaningless design I know, but that's not the point). If I create and save an instance of Item with an associated CashBid, when I query for items the properties defined in CashBid are not retrieved.
NB Bid is not mapped as abstract.
Here is a code snippet:
...
// First Session
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
Bid bid = new CashBid(new BigDecimal(100.0d), "euro");
Item item = new Item("pc");
Serializable bidId = session.save(bid);
item.addBid(bid);
session.save(item);
transaction.commit();
session.close();
// Second Session
session = sessionFactory.openSession();
transaction = session.beginTransaction();
//session.load(CashBid.class, bidId);
Query query = session.createQuery("from Item");
List<Item> list = query.list();
for (Item item_ : list) {
System.out.println(item_);
}
transaction.commit();
session.close();
...
The bid in the item retrieved by the query is a CashBid (that's correct) but the properties that are defined in CashBid and not in Bid are null. If I uncomment the line
//session.load(CashBid.class, bidId);
the problem is not there anymore.
If Bid is not mapped as abstract the problem doesn't show.
My apologies if I'm just missing something very obvious.
Please find the source code and the mappings attached.
