When I run the application, I get this error: 2015-05-24 12:56:30.661 Classifier[2884:1304096] Warning: <NSTreeController: 0x6080001e0500>[object class: NSMutableDictionary] childrenKeyPath cannot be nil. To eliminate this log message, set the childrenKeyPath attribute in Interface Builder 2015-05-24 12:56:39.335 Classifier[2884:1304096] <NSTreeController: 0x6080001e0500>[object class: NSMutableDictionary] Cannot perform operation because childrenKeyPath is nil
Which seems to suggest I need to do something in Interface Builder, but what?
