Hi alls. I've got a problem:
A -- lazy collection of --> B
B -- lazy collection of --> C

When A contains some B objects in collection then i can't retrieve lazy objects C from B.
But when there's null collection of B in A object and i do such thing
a.setBes(new ArrayList())
a.getBes().add(b)
session.update(a);
session.commit();
i can't retrieve c from b - a.getBes().get(0).getCes() .
I've got LazyInitializationException with message "Failed to lazily initialize a collection - no session or session was closed".

What am i doing wrong?

hibernate 2.1.3 or checked out from cvs - 2.1.5

It means that the session you used have been closed meanwhile.

Either use eager fetching or reattach your entities to another session.
