      Hey guys,

      Been banging my head on the keyboard for over an hour with this one - I feel like it's my stupidity, but just not seeing it..
      I've simplified this code a bit, but the process is the same.

      class Foo
  include Mongoid::Document
  has_many :bars

  def add_bar!(name, metadata = { })
    bars.create! :name => name, :metadata => metadata
  end
end

class Bar
  include Mongoid::Document    
  belongs_to :foo
  field :name, :type => String
  field :metadata,      :type => Hash
end

f = Foo.create!
b = f.add_bar!("oh hai", { :something => "blah" })
# at this point, b.metadata looks good, BUT
Bar.find(b.id).metadata.nil? # returns true

      I don't understand how the create! can report that everything has saved OK, yet the Hash data clearly has not been saved?

      Many TIA.
      Rob
