У меня есть 3 класса, где
Пользователи <------ PersonalUser <------ Администратор </p>
пример файла сопоставления пользователей:
<class name="com.BiddingSystem.Models.Users" table="USERS">
</class>
образец личного файла сопоставления пользователей
<joined-subclass name="com.BiddingSystem.Models.PersonalUser" extends="com.BiddingSystem.Models.Users" table="PERSONALUSER" lazy="false" cascade="all">
</joined-subclass>
пример файла сопоставления пользователей с правами администратора:
<joined-subclass cascade="all" name="com.BiddingSystem.Models.Administrator" extends="com.BiddingSystem.Models.PersonalUser" table="ADMINISTRATOR" lazy="false">
</joined-subclass>
но когда я пытаюсь удалить Администратора, я получаю следующую ошибку:
