NSDatePicker cannot display or bind to a nil dateValue so I have put together something that might be of use when binding to NSDate instances that might be nil.

Subclassing NSDatePickerCell is made difficult because NSDatePickerCell does not call - (void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView to draw its interior.
I therefore obscure the controls persistent dateValue by setting the fore and background colours equal.
If anyone can think of a better approach I would be glad to hear it.
Jonathan
