NHibernate disable all-delete-orphan?

You may consider using IStatlessSession Operations performed using a stateless session do not ever cascade to associated instances. Collections are ignored by a stateless session. Operations performed via a stateless session bypass bernate's event model and interceptors.

Stateless sessions are vulnerable to data aliasing effects, due to the lack of a first-level cache. A stateless session is a lower-level abstraction, much closer to the underlying ADO.

In this case IStatlessSession helped me. Thank you. – Marcin May 18 at 8:41 Problem is when object A has to sets: B and C.

B is changed and C is not. When I Save A, I would like to save A and B and not to update C. Is it possible?

To prevent cascade saving, you have to remove the attribute from the mapping. As mappings are built into session factory, there is no simple way to disable cascade temporarily.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
