Bindings validation weirdness

Subject: Bindings validation weirdness

Hi all,

I am having a problem with a date binding. I have a NSTextField bound to a model object property that is an NSCalendarDate and using an NSDateFormatter. When the field displays the date everything works fine. When I type in something weird (like 'fff') and hit return I get two error dialogs with the helpful message "Format error" and 2 buttons (OK, Discard Changes). OK reverts the value and Discard Changes doesn't even accept a click. The dialogs are coming from [NSObject presentError:] so I assume this is a system default error presentation dialog.

So, does anyone have any ideas why I would get 2 of the same dialogs, and why the buttons are not working on either of them?

Thanx,
joe
