NSDatePicker and NSNull

Hello.

I have a Dictionary with different property values for an entity. One of the values are a date, but it can be NSNull. NSDatePicker does not handle the null-value and give the following error message:

Cannot create date from object <null> of class NSNull

What is a good way to handle this situation. Should I have a check box for "has date". Setting it set the default date to something and enables the date picker. Unsetting it disable the date picker. Any other solution?

Regards,
 - Tore.
