title: 2 and more UNIDIRECTIONAL relationship (onetoone)
body: <p>I have a question.</p>
  
  <p>I have 3 entities: <code>member</code>, <code>contact</code>, <code>fine</code> </p>
  
  <p>Member to contact (one to one unidirectional)
  Member to fine (one to one unidirectional)</p>
  
  <p>In the member entity class I've declared</p>
  
  <pre><code>@OneToOne(cascade={CascadeType.PERSIST})
     private ContactEntity contact;
  </code></pre>
  
  <p>when i try to run my app, everything is ok.</p>
  
  <p>but when i try to add in fine</p>
  
  <pre><code>@OneToOne(cascade={CascadeType.PERSIST})
     private FineEntity fine;
  </code></pre>
  
  <p>there is error. </p>
  
  <p>I try searching online and change it to CascadeType.ALL the error still exists.</p>
  
  <p>Am I declaring it the correct way?</p>
