Hi,
I have an (editable) NSTextField with an NSNumberFormatter attached to it. The text field is bound to some other numerical property (if you want to test this, you can just make a simple AppController and put the "@property(readwrite) int foo;" inside it, and bind the text field to AppController's foo).
My problem is that when I type some invalid stuff in the text field, such as some letters "abc", I don't get a beep (which is the normal behaviour and the one I want), but I get some sheet popping up saying "Formatting Error". I don't want this sheet. I want the beep like usual. How can I get rid of this sheet behaviour that the bindings is causing? And why is it even causing it?
Second question: How can I make my text field just disallow entering of invalid characters in the first place (and producing beep when it is tried)? I want, as you probably guessed, a method that is compatible with bindings.
Thanks very much,
U
