  <p>when querying with <code>Projection.fields</code> everything is fine, the returned QBean have fields list with size as expected (2), elements with field references as expected (at last I think it is as expected, for example id field name is "id", type is Long, modifiers is 2 but fieldAccessor is null) and DTO list generated with fetch is filled with id and name correctly. </p>
  
  <p>but, I want to use setters instead of fields so I'm trying with <code>Projections.bean</code>. Usint this projection returned QBean got an empty list of fields and a list setters with same size but all elements are null, DTO list generated by fetch came with id and name null (obviously).</p>
  
  <p>both projections generates a bindings map with size 2 as {"id" -> "city.id", "name" -> "city.name";</p>
  
  <p>Can't figure out what is going wrong. Is the fieldAccessor used to define setters and, as it is null, projection is unable to define them? </p>
  
  <p>I'm using spring framework 4 latest and query is something like this:</p>
  
  <pre><code>...
  QCity qCity = QCity.city;
  return new JPAQueryFactory(sessionFactory.getCurrentSession())
      .select(Projections.bean(CityDTO.class, qCity.id, qCity.name)
      .from(qCity)
      .fetch();
  </code></pre>
  
  <p>any ideas?</p>
  
  <p>edited:</p>
  
  <p>In fact even projecting for City.class result is the same... cant bind values from query using setters...</p>
