Well, you can implement an N-level Undo functionality (like I referred to in my post), or , you can 'delay' the databinding on your WinForms app to get a solution for your problem. My first idea was to implement N-level undo functionality (which I've done) on my base-entity class, but after a little bit of playing with it, I thought it was overkill. (Some of my entities have associations to other entities, etc... so a lot of data would be serialized). Next to that, I didn't want to make all my entities serializable, so I came up with another solution; that is: delaying the 2-way databinding. This problem is not directly related to NH, although I do find it a pity that NH commits the changes you made to an entity when you flush the session, even if you did not call 'SaveOrUpdate' for that entity.
