Is it possible to update all loaded objects with the same ID as a saved object? I want so save an object, the object is loaded several times in the session, if I save one object the other objects will not reload automatically and keep the old information.

I believe this is the standard behavior of the first level cache.

If you load the same object multiple times within the same session, they are all references to one object.

If you load the same object in multiple sessions, well that is what the second level cache is for as I understand it.

If you call session.Refresh(theObject) it should refresh state from the cache if an instance is there, otherwise from the DB, thus loading it in the cache. You could call refresh before each use to ensure that they are in synch with the repository.

If this doesn't do it for you, could you be more specific regarding both what you are trying to to and what the current scenario is?

Hmm, maybe I should describe the circumstance, because this is not what I'm looking for.

In my program I have a class "Variable". With the objects of this class I do several calculations. One Variable can also be an computed value, (VariableComplete.Value = Variable1.Value + Variable2.Value). If now Variable1.Value changes, all Variables using this one have to be refreshed (e.g. VariableComplete), because the value of each variable will be computed only one time, saved in a property, and than used on and on...

I've no Idea how I could handle this. To update all objects of Variable1 will not help...
