I have a couple of MADateDescription to manage the
effective date and
the expiration date of a structure and their values could be either a
valid date or nil.
How does the description-definition of your MADateDescription look
like? I quickly tried on my machine and it works as expected.
3. Delete the content of the field, MADateDescription
complains about
an invalid date format.
Sorry, I am unable to reproduce.
Cheers,
Lukas
