      def view_paths=(paths)
        @view_paths = ActionView::PathSet.new(Array(paths))
      end

        added_resolvers = 0
        self.class.fallbacks.each do |resolver|
          next if view_paths.include?(resolver)
          view_paths.push(resolver)
          added_resolvers += 1
        end

        user_details = @details.merge(options)

        if @cache
          details_key = DetailsKey.get(user_details)
        else
          details_key = nil
        end
