I tried making it 'type=3D"nb"', and I got:

 Invalid empty string value for birthday

I use a script to validate the form fields. I've tried:

if birthday =3D=3D '':
   birthday =3D None

but somewhere it gets turned into the string "None" instead of the
Python value None, and "None" isn't a real date.

So I took the conversion from '' to None out, and got the "Invalid empty
string value for birthday" error.

There must be a way to do this - you couldn't set an integer or float to
'' either. =20
