Thanks so much! I knew it was something stupid that I was doing on my
end and conceptually it seemed like the right structure.

You don't have a breakpoint on objc_exception_throw. That would make
it more obvious that something was going on, since you also didn't see
this showing up in the console window:
2009-05-13 18:00:59.459 OutlineView[694:813] ***
-[_NSControllerObjectProxy fullPath]: unrecognized selector sent to
instance 0x155890
The line that's causing the exception is in your outline view data
source's -outlineView:objectValueForTableColumn:byItem:
implementation:
return (item == nil) ? [[groups selection] fullPath] : (id)[item
relativePath];
Specifically, your use of [groups selection] is the problem.
-selection is documented to return a KVC-compliant proxy object, not
actual instances of your model objects. For that, you want
-selectedObjects.
