If you declare a default, have you checked whether has_enrollment_type() returns
false if the field is not present?

[pastarmovj, 2012/02/16 14:55:21]

Yes. It returns false. The default however will ensure that calling
enrollment_type() even when has_enrollment_type() == false is returning sane
value.
