Hibernate has a special "class" property. How to refer it in QueryDSL?
What I generally need is to group results by the entity type. It is possible to do it in HQL.

You can't use the Hibernate class property, but the JPA type expression instead, via JPAExpressions.type(entity).

it doesn't work with grouping in QueryDSL: `Unsupported expression unknown operation with operator com.mysema.query.jpa.JPQLOps#TYPE and args [sourceTable]` – Martin Ždila Jun 04 '15 at 10:13

Which Querydsl version do you use? And could you provide the full stacktrace? – Timo Westkämper Jun 08 '15 at 17:41
