Marcin Skladaniec commented on CAY-1194:
----------------------------------------
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
