I have a named query:-
@NamedQueries ( {
@NamedQuery(name="byOwners", query="select e from SchedulerEntry e where e.owner.id in ( :loginIdList )")
})

I am calling it like this:-
public List<SchedulerEntry> findEntriesFor(List<Long> owners) {
Query query = getCurrentSession().getNamedQuery("byOwners");
query.setParameter("loginIdList", loginIds);
List<SchedulerEntry> result = query.list();
return result;
}

I get this error:-
Caused by: java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.Long
at org.hibernate.type.LongType.set(LongType.java:42)
at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:136)
at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:116)
at org.hibernate.param.NamedParameterSpecification.bind(NamedParameterSpecification.java:38)

I think I must be doing something stupid but I can't figure out where.

Could someone please tell me where I am going wrong?

Apologies I realised my mistake.
I should be using a syntax like this:-

q.setParameterList("namesList", names);
