Hello,

I have simple set of elements.

Person {
Set<Event> events;
}

Event {
Person person;
String description;
}

I need to do simple query:

Criteria criteria = sesison.createCriteria(Person.class);
criteria.createAlias("events", "event");

criteria.add(Restrictions.or(Restrictions.isEmpty("events"), Restrictions.eq("event.description", "test")));

criteria.list();

With this line:
criteria.createAlias("events", "event");

result is always empty (list size is zero).

What do I do wrong? Isn't it possible to have this OR condition?

Best regards,
Piotrek
