Well, they are related, but perhaps you stumbled on the answer anyway.

NSTextField inherits -stringValue from NSControl, so that's no problem.

But, if you use -setAttributedStringValue:, you should use 
-attributedStringValue to retrieve it. Internally, I do not believe that 
NSControl automatically reduces an attributed string to an ordinary string, but 
maintains them as totally separate values. If there is an attributed string to 
display, it will take that over a plain string, but it does not provide any 
conversion between them.
