Hi I need to implement the optimistic locking without the use of the @Version annotation since I have a legacy database schema here. I looked at the documentation and the book and found a way to do this. But it only applies to one table. I need it to be able to notice when two threads (users) are working with object A and one is modifying an object in Set<B> and one is modifying an object in Set<C>.

I was kinda hoping optimistic locking would also detect that and throw a staleDataException or whatever it's called... but it doesn't. So my question is: How can I achieve that?
