Seeing a stack trace would be helpful. Without any further information,
my guess would be you have a relationship cycle which requires a session
to load. So the first thing I would try is add a session and see if it
helps.

BTW, ODB 2.0.0 and later detect this problem and throw the session_required
exception.
