I used to thought like that too (a couple of hours ago :) ), but I find the approach clumsy when a lot of ajax round-trips are involved; the object is reloaded just for setting a property and discarded again; also, depending on how you configure your transactions, you could end up persisting partial non-validated changes (although I should say that from my observations this doesn't happen inside a vanilla OpenSessionInViewFilter spring setting). I've been coding some examples with convoluted entity lazy-loaded associations and, despite my previous fears, detaching/re-attaching it from/to the hibernate session works like a charm. I think I will tag all my editable entities as Serializable and embrace this approach.
