Saveorupdate is not updating

This method copies the state of the given object onto the persistent object with the same identifier.

If there is no persistent instance currently associated with the session, it will be loaded. If the given instance is unsaved or does not exist in the database, NHibernate will save it and return it as a newly persistent instance.

NHibernate supports this model by providing the method // in the first session Cat cat = (Cat) first Session.

Load(typeof(Cat), cat Id); Cat potential Mate = new Cat(); first Session.

The returned object reflects the changes, and it is attached to hibernate session.

MERGE method offers greater flexibility when it comes to saving data objects, since you need not worry about attaching object to Session.

Many applications need to retrieve an object in one transaction, send it to the UI layer for manipulation, then save the changes in a new transaction.

(Applications that use this kind of approach in a high-concurrency environment usually use versioned data to ensure transaction isolation.) This approach requires a slightly different programming model to the one described in the last section.

Save(potential Mate); // in a higher tier of the application cat.

Mate = potential Mate; // later, in a new session second Session. Update(mate); // update mate if it wants their state also updated.

This can be very tedious issue, since that means if you need to save an object that is not attached to a session, you need to do these.

object must be attached to a hibernate session (including all sub objects within the object), and once save/update is done, the object reflects the updated changes (e.g.
