[jira] Commented: (CAY-1194) problems with relationships when using

Andrey Razumovsky commented on CAY-1194:
----------------------------------------
Marcin,
Thanks for junit test.
This is a harsh issue. I can confirm it can also be reproduced on normal nested DataContexts.
The root of the problem is that when child's to-many property is being resolved, it sends query to parent context - It is intercepted there, because parent object's to-many list is already resolved. So "objectList" in child's PersistentObjectList is parent's PersistentObjectList. That's why all changes are applied without commit. We'll likely need to duplicate the list.. Will need some more time to find a proper fix..

----------------------------------------
public void testCAY1194() throws Exception {
deleteTestData();
ClientMtTable1 parentMt = context.newObject(ClientMtTable1.class);
ObjectContext child = context.createChildContext();
ClientMtTable2 childMt2 = child.newObject(ClientMtTable2.class);
childMt2.setGlobalAttribute("222");
ClientMtTable1 localParentMt = (ClientMtTable1)child.localObject(parentMt.getObjectId(), null);
assertEquals(0,parentMt.getTable2Array().size());
assertEquals(0,localParentMt.getTable2Array().size());
childMt2.setTable1(localParentMt);
assertEquals(0,parentMt.getTable2Array().size()); //* (see notes)
assertEquals(1,localParentMt.getTable2Array().size());
child.commitChangesToParent();
assertEquals(1,parentMt.getTable2Array().size()); //** (see notes)
// notes:
// if the * test is removed, but the call to parentMt.getTable2Array().size() is executed ** will fail, the parent table will be linked to 2 records instead of one, moreover, the context of one of the related objects will not match the parent record context
