SubSonic, ошибка скаффолда

Question

Я использую Scaffold для управления данными из моих таблиц, используя subsonic 2.1. только для одной таблицы я получил это сообщение об ошибке, когда пытаюсь просмотреть данные таблицы, я воссоздаю связанные классы несколько раз, но все же и только для скаффолда Я получил эту ошибку, я могу использовать класс таблицы и самостоятельно вставлять / редактировать данные. В моей таблице есть поля nvarchar и bigint. В чем дело?

 Error converting data type nvarchar to bigint.
