Ronak Patel commented on HHH-6695:
----------------------------------

I hope this will be taken care of in hibernate-release 4.0.0. This has been a bug that's been around hibernate for at least a year; if not more. One of the most infamous ones...

>             Project: Hibernate ORM

> The already closed issues HHH-5348 and HHH-6591 only fixed the bug with standard (non-named) queries. Having a query like {code:sql}SELECT NEW org.test.MyClass( 'Foo', 123 ) FROM IrcEvent ev{code} as shown in HHH-6591 used by createQuery(), the bug has been fixed. Using the very same query as a named query by createNamedQuery() this exception is thrown:
> {noformat}
> java.lang.IllegalArgumentException: Cannot create TypedQuery for query with more than one return
>         at org.hibernate.ejb.AbstractEntityManagerImpl.createNamedQuery(AbstractEntityManagerImpl.java:684) ~[hibernate-entitymanager-4.0.0-20110929.060732-144.jar:4.0.0-SNAPSHOT]
