FIXED issue with sending the 'get_member' message to a nil relation

    # If the original also happens to be an alias, continue recursively.

    def find_original(al)

      al_def = al[:alias]

      orig = @relations[al_def[:cls]].get_member(al_def[:member], al_def[:type] || al[:tagname])

      orig = @relations[al_def[:cls]]

      return al if not orig

      orig = orig.get_member(al_def[:member], al_def[:type] || al[:tagname])

      if orig[:alias]

        find_original(orig)

      else

        orig

      end

    end

  end
