sub table patcon: enter image description here

the implement patrefmanagerprop.getbyid enter image description here

anytime i've seen has been caused attempt access lazily loaded collection when isession used retrieve object has been disposed or no longer exists.

you can fix attaching entity session using isession.lock(entity, lockmode.none).

just note of warning - can't attach transient entity session.

(great detail in original question way. +1 that)
