Hql "in" statement doesn't work with an @ElementCollection

I have a class collection property with @ElementCollection and @Enumerated(EnumType.ORDINAL)

I am trying to perform an in statement on that collection however in the generated sql i get this -> {non-qualified-property-ref} in (?)

I might be doing something wrong while creating the hql itself. Could it be because the elements are actually enum values ?

Thanks,
Peter
