Debugging IB Errors



Folks;

I'm getting the following error during my app's launch:
<NSTableColumn 0x3c87880> valueForUndefinedKey:]: this class is not key value coding-compliant for the key value


What is the best way to resolve where this TableColumn is?
BTW: Run or Debug does not matter. The error simply stops the app dead. No debugger is ever raised.


My nib is getting complex; it's got a lot of objects at the moment.
Through caveman NSLog messages I have narrowed to a suspicious NSView subclass.
I have been over and over the 11 NSTableView objects in this view and cannot find any binding or identifier which is 'value'.
A NiB search yields no joy.


So how do the pros go about cornering a beastie like this?

Many Thanks,
Steve
