Subject: Re: soap4r mapping problem when using google adwords api

adding some debug in proxy.rb
    def response_doc_lit(body, mapping_registry)
            puts "in proxy mapping = #{mapping_registry.inspect}"
      body.collect { |key, value|
        Mapping.soap2obj(value, mapping_registry)
      }
    end

shows that the mapping does not contain any information about the adwords types
in proxy mapping = #<SOAP::Mapping::WSDLLiteralRegistry:0x6eea34
@excn_handler_obj2soap=nil,
@schema_element_cache={GetAllAdWordsCampaigns=>[{"dummy"=>"SOAP::SOAPInt"},
[]]}, @schema_attribute_cache={GetAllAdWordsCampaigns=>nil},
@definedtypes=#<XSD::NamedElements:0x2a56fc
@cache={#<XSD::QName:0x3706ca {}dummy>=>nil, #<XSD::QName:0x3766b0
{https://adwords.google.com/api/adwords/v2}getAllAdWordsCampaigns>=>nil},
@elements=[]>, @definedelements=#<XSD::NamedElements:0x2a56fc
@cache={#<XSD::QName:0x3706ca {}dummy>=>nil, #<XSD::QName:0x3766b0
{https://adwords.google.com/api/adwords/v2}getAllAdWordsCampaigns>=>nil},
@elements=[]>, @excn_handler_soap2obj=nil>

Is the init generated by wsdl2ruby correct?
  if RUBY_VERSION > "1.7.0"
    def add_method_interface(name, param_count)
      ::SOAP::Mapping.define_singleton_method(self, name) do |*arg|
        unless arg.size == param_count
          raise ArgumentError.new(
          "wrong number of arguments (#{arg.size} for #{param_count})")
        end
        call(name, *arg)
      end
      self.method(name)
    end
