[Zope] Can't update properties of a custom product

Hi,

I finally found where my problem comes from ; I noticed that the exception 
response headers was containing references to the file which raised the 
exception : DateTime.py, line 655 !!
After looking at the code and making a few more tests, I finally found that 
Zope don't accept 'None' or empty values for 'date' properties : you have to 
enter a valid date for date properties !!

So my new question is simple : as en empty value is significant in several 
cases for this product, how can I handle empty date properties, without using 
string properties which will be converted as date in internal properties ??

Thanks,

 Thierry
