Dear Sirs

The hql query below work fine:

String query = "select t from TextVersion as t where version = " +
"(select max(version) from TextVersion where headline_id = " +
headlineId + ") and headline_id=" + headlineId;

List textVersions = hibernateSupport.findByHQL(query);

the POJO class is TextVersion and I am able to retrieve objects from this class in List textVersions.

I need to replace this query by Criteria using Restriction and Projection classes:

DetachedCriteria criteria = DetachedCriteria.forClass(TextVersion.class);

criteria.setProjection(Projections.max("version"));
criteria.add(Restrictions.eq("headlineId", headlineId));

List textVersions = hibernateSupport.findByDetachedCriteria(criteria);

The problem is that I receive Integer objects represented the "version" field of the TextVersion that I need to retrieve in List textVersions.
This Integer values are the same that these ones of TextVersion objects that I need to retrieve, but I need of all TextVersion
objects not only filed 'version'.

What is necessary to set Criterion or Projection to get all the objects?

best regards
