title: Can I save one object twice in a same transaction,using hibernate?
body: <p>Same as the title says. I met the problem. I begin a transaction and save an object twice, then I get this exception:</p>
  
  <pre><code> "org.hibernate.NonUniqueObjectException"
  </code></pre>
  
  <p>And the object is not selected from db.the first save means "insert into", the second save means "update".</p>
