Hey Rainer -

Great question!  What you found is pretty much exactly what I would have
recommended.  I don't *think* you actually need the :use_transactions option
-- you should just be able to override the action (as you've done) and call
it a day.

The one alternative is that you can completely turn off all of the
ActiveRecord features or explicitly force state_machine to treat the
integration like an ActiveModel integration which will avoid creating
things like named scopes.  For example:

state_machine :form_step, :initial => :field_type_step, :integration =>
:active_model do
  ...
end

Hope this helps and best of luck!

Best,
Aaron
