What makes you think you can? Logically, you shouldn't be

imagine selectedObjects is always going to return an index set; it'd
just be empty with no selection. I did try comparing it to
NSNoSelectionMarker just in case, and that doesn't work.
Perhaps instead of imagining it would be more helpful to read the
documentation. -[NSObjectController selectedObjects] returns the
actual objects.
You also don't seem to understand how bindings work. Even if -
selectedObjects did return an NSIndexPath, it's a KVO-compliant
property and therefore perfectly suitable for binding to.

I mixed up selectedIndexes. So, yes, it does return objects.
However, it does not in fact return the actual objects. It returns
proxies. Which is what I said in my original post. So even if there
are no selected objects, you get back a non-empty array.
-[NSArrayController selectedObjects] does not return proxies, it
returns the real thing. On the other hand:
-[NSArrayController selection] returns a proxy that represents the
overall selection
NSTreeController uses proxies to represent its tree structure. On
10.5+ this is exposed as NSTreeNode.
I think there is some confusion here between these things.
