My experiments show that NSNumberFormatter does not tolerate grouping
separators in input text. Or at least I wasn't able to force it.
On another subject, I'd recommend that you never pass currency amounts through
a double. You have a formatter attached to your field. Set it to always return
an NSDecimalNumber (it's in the Mac OS X 10.4+ Custom inspector), and use the
objectValue method of the text field to retrieve the decimal number directly.
