Hibernate version:
3.1.rc2
Mapping documents:

Code between sessionFactory.openSession() and session.close():

DetachedCriteria techIDs = DetachedCriteria.forClass(Technologies.class)
.setProjection( Property.forName("techID") ).add( Property.forName("group").eq( group ) );

List test = session.createCriteria(AutoEval.class)
//.add( Subqueries.in("techID", techIDs) )
// .add( Property.forName("techID").eqAll(techIDs) )
.add( Subqueries.propertyEqAll("techID", techIDs) )
.list();

I used the below code to see if DetachedCriteria is corect :

Criteria criteria = techIDs.getExecutableCriteria(session);

list = criteria.list();

and it is.
