I have a form with a PopupDateTimeField, and a dataobject with a SSDatetime, but if I try and run
$form->SaveInto($release)
I get the error [Notice] Undefined property: Release::$DeliveryTime.
This also happens if i change it to just date, but not if i change it to text (but of course then the date functions don't work)
How do I get this to work?
