Shoulda's matcher validate_uniqueness_of(:name) does not work

[greyblake]

My env:

• Rails 3.1
• Ruby 1.8.7

I've got the next model:

class Submodel < ActiveRecord::Base
  acts_as_enumerated :name_column => :code

  validates :code, :presence => true, :uniqueness => true
  validates :name, :presence => true, :uniqueness => true
end

I've got the next RSpec test:

describe Submodel
  before(:all) do
    Vehicle::Make.enumeration_model_updates_permitted = true
    @make = Factory('vehicle/make')
  end

  it { should validate_presence_of   :code }
  it { should validate_uniqueness_of :code }
  it { should validate_presence_of   :name}
  # NOTE: validation for :name column don't work when acts_as_enumerated is used
  it { should validate_uniqueness_of :name}
end

When I run it I've got the 4th test failed (all other are passed):

1) Submodel validations 
   Failure/Error: it { should validate_uniqueness_of :name}
     Expected errors to include "has already been taken" when name is set to "unique_string_5", got errors: code can't be blank (nil)name can't be blank (nil)

I'm having a very simular issue: thoughtbot/shoulda-matchers#58

I switched to a supported fork (power_enum): https://github.com/albertosaurus/enumerations_mixin

I have the same issue.
