Array_Of_Int in SOAP client

Question

I have a very interesting issue when I call a SOAP method with my client, I must pass a parameter which is of type Array_Of_Int(Array_Of_Int = array of Integer), the problem

Answer 1

Since no one cares to post their answer or have no other idea on how to fix this issue, I'll just post my fix until others can come out with a more elegant solution than editing the request.

Make sure the next line of code is added in the initialization section of the *.pas file generated when you imported the WSDL file(big thanks to Bruneau for pointing this out)

InvRegistry.RegisterInvokeOptions(TypeInfo(), ioDocument);

However that imposes another issue, the namespace, as a quick and pretty elegant fix, I've added the following code in the THTTPRio's OnBeforeExecute method

procedure TMyDataModule.MyRioBeforeExecute(const MethodName: string; SOAPRequest: TStream);

  procedure FixNamespaces;
  var
    LStrings: TStringList;
  begin
    LStrings := TStringList.Create;
    try
      SOAPRequest.Position := 0;
      LStrings.LoadFromStream(SOAPRequest);
      SOAPRequest.Position := 0;
      SOAPRequest.Size := 0;
      LStrings.Text := StringReplace(LStrings.Text, MethodName, 'NS1:' + MethodName, [rfReplaceAll]);
      LStrings.Text := StringReplace(LStrings.Text, MethodName + ' xmlns', MethodName + ' xmlns:NS1', []);
      LStrings.SaveToStream(SOAPRequest);
      SOAPRequest.Position := 0;
    finally
      FreeAndNil(LStrings);
    end; // tryf
  end; // procedure FixNamespaces;

begin
  FixNamespaces;
  // other possible issue to be fixed -- if any
end;
