Господа, подскажите пожалуйста - где копать, а то даже ошибку толком прогуглить не могу, и не понимаю, из-за чего она появляется..
Ситуация такова: Ниже приведенные сущности не стартуют в проекте, если только вытянуть 3 сущности в отдельный проект, то всё стартует. Не могу понять, почему то же самое в проекте с другими сущностями стартует..
