title: org.hibernate.MappingException: Repeated column in mapping for entity. Hibernate Mapping Exception
body: <p>I have 2 tables: Accounts and AccountDetailsData. I mapped there are to 2 classes:</p>
  
  <pre><code>@Entity

  <p>When I run this code:</p>
  
  <pre><code>Session session = getCoreObject().getDataBase().getCoreSession();
  AccountsEntity fieldsEntity = (AccountsEntity) session.load(AccountsEntity.class,1);
  </code></pre>
  
  <p>I have exception:</p>
  
  <blockquote>
    <p>org.hibernate.MappingException: Repeated column in mapping for entity: com.company.hrplus.core.rest.Account.enteties.AccountsDetailDataEntity column: id (should be mapped with insert="false" update="false")</p>

  <p>I can't understant where is the problem. Please help.</p>
