    BTW, you may still use custom validation for such check here
    (overriding DataObject.validateForSave()). An obvious advantage over a
    UNIQUE constraint DB exception is that you can present user with a nice
    meaningful error message. A disadvantage - an extra SelectQuery before
    commit.
