DragDrop COPY Bug (with fix)

Question

If you read the quick start on drag/drop:
http://www.adobe.com/devnet/flex/quickstart/adding_drag_and_drop/
it states:
quote:
Copying items by using the drag-and-drop operation
The following example lets you copy items from one List
control to another by dragging them. You can copy the same item
multiple times from the drag initiator to the drop target.
However, even in the sample movie, this does not work... if
you copy the same item multiple times, it does not truly do a copy
and just adds a reference to the same object, thus you can only
ever rollover/select one of the instances and the others cannot be
interacted with.
To correct this, the following code should be replaced on
line 7277 of mx.controls.listClasses.ListBase:
original:
for (i = items.length - 1; i >= 0; i--)
collectionIterator.insert(items
fixed:
for (i = items.length - 1; i >= 0; i--)
if(event.action == DragManager.COPY)
var clone:ByteArray = new ByteArray();
clone.writeObject(items);
clone.position = 0;
collectionIterator.insert(clone.readObject());
else
collectionIterator.insert(items
Hopefully Adobe can fix this in the core SDK

Same problem in Pages (and it's been updated to the latest version, too). I haven't set any keyboard shortcut changes in the keyboard preferences pane, either. Quite strange!
