creator not set until after validation

[jmccaffrey]

Is there any reason why the stamper couldn't be set before validations?

I have a case where I want to ensure that a creator doesn't already have an object, but the creator id doesn't get set until after validations.

I changed stampable.rb to have before_validation :set_updater_attribute before_validation_on_create :set_creator_attribute

Is there a reason why this is a bad idea? (sorry if this covered in a google group already)
