Can I rollback object state with nHibernate transaction

i have object A that have collection of objects B, each of them have collection of objects C

scenario 1.- Existing A ,
- add new B object,
- add new C object to the B object
- Rollback

result:A have full ierarchy of objects A->B->C not rolled back. ( but in DB nothing present. )
workaround:
Session.Refresh( A ) help in this case.


scenario 2.- Existing A ,
- Existing B ,
- Add new C to B
- RollBack

result:
as in scenario 1.
workaround:
Session.Refresh( A ) DOES NOT help in this case. it refresh only A level
and not refresh B. need refresh all B objects separately


in Big Hiearhy of object it is hard. need method that can recursive refresh objects.

Transaction.Rollback() doesn't affect your entities; it is related to the Database operations you made.

What you can do to get your entities as they were, is to load them again (NHibernate will use its caches to create them...)
