I'm getting a crash in -[NSTableView _isGroupRow:] in my unit tests if I try to run the main run loop.
In my document's window, I have an NSOutlineView with its delegate and dataSource set to the window controller. In some unit tests, I want to run the main event loop to give some bindings a chance to do their thing, but this causes a crash. Once, instead of crashing, there was a message logged that some random class (whose name I can't remember) doesn't respond to -[outlineView:isGroupItem:], as if the outline view's delegate were set wrong. I added a check for that in the unit test and it was fine. When I run the app normally everything works.
I create the document by calling [[NSDocumentController sharedDocumentsController] openUntitledDocument:YES error:&e]. Is there something else I need to do so that everything get set up correctly?
