rails_admin ArgumentError when trying to edit or create a new entry

I'm getting this error while trying to create a new or edit a Limitation (model below)

ArgumentError in Rails_admin/main#new

Showing /Users/deini/.rvm/gems/ruby-2.0.0-p195/gems/rails_admin-0.4.9/app/views/rails_admin/main/_form_filtering_select.html.haml where line #11 raised:

wrong number of arguments (0 for 1+)

Extracted source (around line #11): (selected_id = field.selected_id)

    selected_id = selected.send(field.associated_primary_key)
     selected_name = selected.send(field.associated_object_label_method)
   else
     selected_id = field.selected_id
     selected_name = field.formatted_value
   end

System.rb

class System < ActiveRecord::Base
  has_many :attachments

  has_many :limitations
  has_many :companies, :through => :limitations

  accepts_nested_attributes_for :attachments
  accepts_nested_attributes_for :companies

  attr_accessible :conf_type, :version, :hardware_type, :name, :attachments_attributes, :company_ids, :companies_attributes

  rails_admin do
    list do
      exclude_fields :created_at, :updated_at
    end
  end

end

company.rb

  class Company < ActiveRecord::Base
  belongs_to :distributor
  has_many :users, dependent: :destroy

  has_many :limitations
  has_many :systems, :through => :limitations

  accepts_nested_attributes_for :limitations

  attr_accessible :distributor_id, :name, :system_ids, :email, :limitations_attributes

  rails_admin do
    list do
      exclude_fields :custom_url, :created_at, :updated_at
    end

    edit do
      exclude_fields :custom_url, :users
    end
  end

end

limitation.rb

class Limitation < ActiveRecord::Base
  belongs_to :company
  belongs_to :system
  attr_accessible :company_id, :system_id, :version_limit
end

I haven't modify anything in my rails_admin, any ideas of what I'm doing wrong?

Actually i too got the same error. But then when i changed the name System to some other name in my entire code including model,table name and all, my code starts to work fine. Try changing the name System with some other word.
