App instances don't show choice options???

(Bug, Investigate , Priority: Critical, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Summary: I extracted an App from this Space, to create an Issues Space for Arisia. That mostly looks okay, but Issue Kind, Issue Closed Reason, Priority and so on aren't displaying any values!!!
Note that the App itself does have these values -- they just aren't displaying in the child Space. They aren't showing as options in the Editor, and aren't showing in Show All Things. This probably implies that they aren't getting shadowed right?
Yes, it looks like they aren't being shadowed at all. When I look at the child Model, the Instances that get listed are those of the parent App, and there aren't any local ones.
Actually -- they probably shouldn't shadow, in general. These Choice Values should be directly inherited, and we probably don't want to duplicate. The correct solution is probably that, when we gather up the available options, if the Property is shadowed, it should include the options from the parent App.
