I've spent few hours on trying to make datefield work, but with no success.
My problem is that when try to save a datefield in a gridfield it always set month to 00, and set the value in the database to 01. I Tried many different dateformat for eg. 'd.m.Y' but it doesn't work.
I use version 3.01 but it seems that this happens also in 3.02 + in 3.02 populateDefaults doesn't work.
