Validation issue in 0.14.3

Hi,

I have a model as follows:

class CancellationNotification < ActiveRecord::Base

Relationships

belongs_to :originator
belongs_to :cancellation

Validations

validates_presence_of :originator_id, :cancellation_id
end

As part of my unit test I check that passing no information to
CancellationNotification.create() fails validation, But the
originator_id does not fail validation. If I change its name it’s
fine. Have I clashed with some new “special” AR value or something?
This worked in 0.13.1

Kind regards,
Steven
