Hmm... why then do I get "detached object passed to persist" when I try to persist a newly created entity with collection mapping?

I can persist anything just fine, but when I create an entity that holds a List of other entities (even when the list is still empty), that fails.
I have already tried to merge() the entit instead of persisting it, but then em.find will return null for it while still in the same transaction. I would expect to see and use the entity later on to fill that collection...

I am confused,
