has_many :through with acts as list

[ldonnet]

I want to use your acts as list gem with these models :

module ActiveRoad
  class PhysicalRoad < ActiveRoad::Base
    has_many :physical_road_junctions
    has_many :junctions, :through => :physical_road_junctions, :dependent => :destroy, :uniq => true
  end
end

module ActiveRoad
  class PhysicalRoadJunction < ActiveRoad::Base
    attr_accessible :position  

    belongs_to :physical_road
    belongs_to :junction

    acts_as_list :scope => :physical_road
  end
end

module ActiveRoad
  class Junction < ActiveRoad::Base
    has_many :physical_road_junctions
    has_many :physical_roads, :through => :physical_road_junctions
  end
end

But when I use the scope of acts_as_list an exception is raised :

ActiveRoad::Junction junction connected to physical roads #physical_roads should be addable
     Failure/Error: subject.physical_roads << new_road
     NameError:
       uninitialized constant ActiveRecord::NamedScope
     # (eval):25:in `scope_condition'
     # ./spec/models/active_road/junction_spec.rb:18:in `block (4 levels) in <top (required)>'

Should we use this gem in a special way with has_many :through relations?

This might be something to do with the namespacing of classes under the ActiveRoad module. I followed an exact same setup, without the module, and it worked for me.

I dig deeper into this problem and acts_as_list is not the guilty. It's an other plugin I use postgis_adapter. Sorry to have disturbed you with this problem and thanks for your help.
