title: How I get a Set<Object> using QueryDSL?
body: <p>I have an Person entity mapped here, inside this entity I have a set of roles (Set roles) mapped with JPA Annotations, ok... Well, I can't get the set of roles from this commmand using QueryDSL:</p>
  
  <pre><code>Set&lt;Role&gt; roles = query.from(qPerson).where(qPerson.login.eq(userName)).uniqueResult(qPessoa.roles);
  </code></pre>
  
  <p>Is that possible? What do you suggest? Thanks for all.</p>
