Requality

1. На узле проекта создаем атрибут "attr1", тип ENUM_DEFINITION, список значений пустой. И создаем атрибут "attr2", тип ENUM_DEFINITION, список значений заполняем, он НЕ пустой.
2. На проекте открываем настройки -> вкладка "Mandatory Attributes". Открываем список "Type".
Видим, что в списке есть "@attr1".

Ожидается, что пустого ENUM в списке доступных типов не будет, как это реализовано для обычных атрибутов в узлах проекта.

3. Выбираем в этом списке "@attr1", возникает сообщение об ошибке:

An error has occurred. See error log for more details.

4. При этом если выбрать сначала непустой ENUM-тип "attr2", а потом снова "attr1", то такой проблемы не будет, но значение по умолчанию останется от "attr2". И после нажатия кнопки со стрелочкой "влево" значение в поле "Type" изменится на "attr2". В итоге обязательный атрибут будет создаваться по нему, а не по "attr1".
