I agree. Each time I get a Zope update I have to edit Converters.py

What I want is something like :empty_as_none

So a float, int or date field will be passed as None if the fields are blank, 
rather than having the converter raising an exception.

ignore_empty doesn't work, because then the field isn't passed in the 
Record at all. 

I use SQLDict as the backend for all my forms (wow, it's great), so None 
really is needed for every field if its blank. If I have ignore_empty, then that 
field doesn't get updated in the database, so if someone wants to blank 
out a field, they can't do it.
