appDisplay: Handle null value

The value can not actually be null at that point, but it's too
hard to spot for tools like coverity:
 - before setting view, we chain up to the parent's acceptDrop()
 - that calls _canAccept(), which we override and check for the view

Still, and extra ? doesn't hurt, and hopefully will make the tooling
happy.
