I have a DatePicker component in a DonorsResource form, that lets you chose a birthdate for a new donor.
However, this field is optional. When the column is null, and you chose to edit a donor, the DatePicker has the date 01/01/1970 pre-filled.
Is there any way, in this case, to assign it the default "dd/mm/yyyy" that's present in the "New Donor" form?
