ClassCastException: PersistentObjectSet as PersistentObject
Hello all,
I was trying to use java.util.Set as the base of my relationships as my GUI
framework uses it a lot. The problem was that on this piece of code:
// TODO: Andrus 1/31/2006 - IncrementalFaultList is not properly
// transferred between contexts....
List childObjects = new ArrayList(objects.size());
Iterator it = objects.iterator();
while (it.hasNext()) {
Persistent object = (Persistent) it.next();
childObjects.add(targetContext.localObject(object
.getObjectId(), object));
}
which is on ObjectContextQueryAction.java, the Persistent object =
(Persistent) it.next(); returns a Set instead of a single item. When I
change the relationship on the Modeler to use Lists everything returns to
normal.
Is this a bug?
Regards
Bruno Santos
