I'm already using some parts of the Wonder frameworks so I'm going to go
with Alan's suggestion of using the ERCStampedEnterpriseObject class as
I just glanced at the code and it overrides willInsert(), willDelete()

By the way, isn't modification of EOs in the validateFor() methods a
cardinal sin in the EOF world?
