Hi Chaps Ran into a puzzle in Aaron's book (Page 327 checking partial strings in the Formatter for the typing tutor example) I added the method - (BOOL)isPartialStringValid:(NSString *)partial newEditingString:(NSString **)newString errordescription:(NSString **)error { . . . stuff }

but cannot see how it ever gets called. Am I missing something or is the book missing something.

You're missing something. That method is part of the NSFormatter protocol* which you're implementing. Cocoa calls this method from invisible parts of the runtime, just like drawRect: gets called on a NSView.

*: It's not technically so much a protocol as an abstract class, if you want to be picky about it. _______________________________________________
