Пытаюсь втянуть wsdl-ссылку в Delphi 2010 через WSDL-Importer (File->New->WSDL-Importer).
Втянутый в Delphi сервис выглядит так:

Код:

// ************************************************************************ //
// The types declared in this file were generated from data read from the
// WSDL File described below:
//
// Encoding : UTF-8
// Version  : 1.0

// ************************************************************************ //

unit vaphoto;

interface

uses InvokeRegistry, SOAPHTTPClient, Types, XSBuiltIns;

type

  // ************************************************************************ //
  // The following types, referred to in the WSDL document are not being represented
  // in this file. They are either aliases[@] of other types represented or were referred
  // to but never[!] declared in the document. The types from the latter category
  // typically map to predefined/known XML or Embarcadero types; however, they could also 
  // indicate incorrect WSDL documents that failed to declare or import a schema type.
  // ************************************************************************ //
  // !:string          - "http://www.w3.org/2001/XMLSchema"[Lit][Gbl]
  // !:string          - ""[Lit][]

  param_1         =  type string;      { "urn:vaphoto"[Lit][GblElm] }
  param_2         =  type string;      { "urn:vaphoto"[GblElm] }

  // ************************************************************************ //
  // Namespace : urn:vaphoto
  // soapAction: urn:vaphoto/getFileList
  // transport : http://schemas.xmlsoap.org/soap/http
  // style     : document

  // service   : vaphotoService
  // port      : vaphotoPort
  // URL       : http://catalog.тра-ля-ля.com/тра-ля-ля.php
  // ************************************************************************ //
  vaphotoPortType = interface(IInvokable)
  ['{BCC8D094-20D9-D36C-1801-68DAD324A546}']

    // Cannot unwrap: 
    //     - Input message has more than one part
    //     - Output part does not refer to an element
    function  getFileList(const dir: param_1; const partcode: param_2): string; stdcall;
  end;

function GetvaphotoPortType(UseWSDL: Boolean=System.False; Addr: string=''; HTTPRIO: THTTPRIO = nil): vaphotoPortType;


implementation
  uses SysUtils;

function GetvaphotoPortType(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): vaphotoPortType;
const
  defWSDL = 'http://catalog.тра-ля-ля.com/тра-ля-ля.wsdl';
  defURL  = 'http://catalog.тра-ля-ля.com/тра-ля-ля.php';
  defSvc  = 'vaphotoService';
  defPrt  = 'vaphotoPort';
var
  RIO: THTTPRIO;
begin
  Result := nil;
  if (Addr = '') then
  begin
    if UseWSDL then
      Addr := defWSDL
    else
      Addr := defURL;
  end;
  if HTTPRIO = nil then
    RIO := THTTPRIO.Create(nil)
  else
    RIO := HTTPRIO;
  try
    Result := (RIO as vaphotoPortType);
    if UseWSDL then
    begin
      RIO.WSDLLocation := Addr;
      RIO.Service := defSvc;
      RIO.Port := defPrt;
    end else
      RIO.URL := Addr;
  finally
    if (Result = nil) and (HTTPRIO = nil) then
      RIO.Free;
  end;
end;


initialization
  InvRegistry.RegisterInterface(TypeInfo(vaphotoPortType), 'urn:vaphoto', 'UTF-8');
  InvRegistry.RegisterDefaultSOAPAction(TypeInfo(vaphotoPortType), 'urn:vaphoto/getFileList');
  InvRegistry.RegisterInvokeOptions(TypeInfo(vaphotoPortType), ioDocument);
  InvRegistry.RegisterInvokeOptions(TypeInfo(vaphotoPortType), ioLiteral);
  RemClassRegistry.RegisterXSInfo(TypeInfo(param_1), 'urn:vaphoto', 'param_1');
  RemClassRegistry.RegisterXSInfo(TypeInfo(param_2), 'urn:vaphoto', 'param_2');

end.

Вроде бы все нормально втягивается , но при попытке вызвать метод веб-сервиса получаю ошибку:
---------------------------
Debugger Exception Notification
---------------------------
Project Project1.exe raised exception class ERemotableException with message 'Procedure 'param_1' not present'.
---------------------------
Break Continue Help

Что я делаю не так? Уже весь мозг сломал.....
