Well, chief, fortunately I didn't have to do that.

The problem was that I had implemented  validateForInsert:
(NSError**)error.  I was returning NO, but ^I^ was not setting that 
NSError.  When I did, I then got it back in save:, as expected.

Apparently, if -validateForInsert: returns NO, save: simply passes on 
whatever error it gets, or doesn't get.  Not ideal behavior, but not a 
bug.  Something like, "You didn't give me an error in -
validateForInsert:, Stupid" would be better.

Thanks,

Jerry
