Ondra Žižka commented on HHH-5348:
----------------------------------
Still have the same problem in 3.6.4:
return em.createQuery("SELECT NEW " + ChannelLogInfo.class.getName() +
"( ev.channel, COUNT(*) AS count, MIN(ev.when) AS first,
MAX(ev.when) AS last )"
+ " FROM IrcEvent ev GROUP BY ev.channel ORDER BY ev.channel",
ChannelLogInfo.class).getResultList();

I'm getting a
java.lang.IllegalArgumentException: Cannot create TypedQuery for query with more than one
return
with a query that returns a View object.
AbstractEntityManager:279, detects as many returns type as there is parameters in the
View object, instead of one single result type, the View Object itself.
QueryString example that fails with public <T> TypedQuery<T>
createQuery(String jpaqlString, Class<T> resultClass):
"select new WorkContractDto(wc.workContractStartDate, wc.workContractEndDate,
wc.workContractEmployeeLastName, wc.workContractSendingStatus) from WorkContract wc where
wc.workContractEmployeeLastName = ?1"
