> Constructor queries (SELECT NEW xyz(a,b)...) with more than one parameter in the constructor are resulting in an java.lang.IllegalArgumentException: Cannot create TypedQuery for query with more than one return.
> Code snippet for testing:
> List<ListResult> resultList = em.createQuery("SELECT NEW domain.results.ListResult(p.name, p.adress) FROM Person p", ListResult.class).getResultList();
> Moreover queries with one paramater in ctor result in an 
> java.lang.IllegalArgumentException: Type specified for TypedQuery [com.evva.keyxs.backend.domain.results.ListResult] is incompatible with query return type [class java.lang.String]
> at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:286)
> More on this in HHH-5348. Its not fixed yet.
