Невозможно установить имя поля "FieldName" для компонента "LookupDataControl"

Господа

Сложилась ситуация, когда в карте редактирования надо обеспечить пользователю возможность выбора некоторой сущности из другого набора данных.

В не визуальные компоненты окна - добавил необходимый набор данных, на форме разместил компонент LookupDataControl, для свойства DatasetLink - указал добавленный мной набор данных. Но при установке свойства DataFieldName - в журнал выбрасывается ошибка
"Невозможно установить имя поля "FieldName" для компонента "LookupDataControl""
В наборе данный ключевое поле, и первичное поле для отображения установлены.

В чём может быть причина ошибки?

С уважением
Егор

Хотел использовать простой LookupControl, но при открытии окна выходит ошибка иного рода.

0x8000ffff - TSObjectLibrary.DBDataset: Ошибка открытия источника данных "ds_OrderGiftsList".

Оригинальное сообщение об ошибке: All queries combined using a UNION, INTERSECT or EXCEPT operator must have an equal number of expressions in their target lists

Егор, что представляет собой sq_OrderGiftsList, он содержит union-ы?
Если содержит, проверьте чтобы все union содержали одинаковое количество колонок с одинаковым набором свойств.

Вот такая страшная штука.
Этот sq был создан давно, и каким то образом функционирует в системе.
Но как только я захотел получить набор данных на его основании, он выдал ошибку.

Yegor, первое что бросается в глаза - заголовок 10-й колонки в первых 3-х подзапросах (union) GiftTypeID, а в последующих TypeID, что некорректно.
Вам нужно изменить заголовки и свойства колонок в запросе таким образом, чтобы они были одинаковы во всех union-х.
