Проблема с массивами SOAP Delphi

У меня есть приложение SOAP, созданное с помощью delphi.

На сервер поступают правильные данные. Но вывод всегда пустой. r объект (ответ) создан, но длина (r.notes) всегда 0. Если я делаю приложение без массивов, оно также работает правильно. В чем проблема? 3 дня поиска в Google и разных комбинаций не помогли.
