Sorry for the late response, I believe
that when you get the dataForFormat(“items”) you receive a copy of
the items *each time.* So the
next time somebody asks for dataForFormat(“items”) they’re
getting a new copy, thus not seeing your changes. The DragProxy itself I don’t
think is going to pay any attention to what you do, it’s a relatively
static image once it starts dragging.
