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. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
