nhibernate: uninitialized surrogate upheld save() cascade

i keep removing an nhibernate.persistentobjectexception job session.save() due an uninitialized surrogate upheld save(). i fiddle cascade settings i away, nonetheless following child objects aren't being saved.

the wholly repair i have found adding following defaultsaveeventlistener.

    stable overrule bool reassociateifuninitializedproxy(object obj, global::nhibernate.engine.isessionimplementor source)
    {
        (!nhibernateutil.isinitialized(obj))
            nhibernateutil.initialize(obj);

        relapse base.reassociateifuninitializedproxy(obj, source);
    } 

this apparently an ideal solution.

any ideas?
