Добрый день, подскажите пжл

Есть проект Infopath 2007. Есть подключение данных к сервисам и к спискам sharepoint 2007,

Подключение к спискам проходят без проблем, заполняю форму, и нажимаю кнопку (обработчик не связано к правилам),

Вылетает ошибка, в чем может быть проблема? Отправка данных на библиотеку не использую

смотрю через debug (breakpoint), до кода не доходить

В логах пишет так

Unexpected end of file while parsing Name has occurred. Line 1, position 1019.

System.Xml.XmlException: Unexpected end of file while parsing Name has occurred. Line 1, position 1019.
