The irony here is that I'm using Merge to try and recover from a
StaleObjectStateException!
I'm using of r4098 from the NHibernate trunk.
Here's the test case:
[Test]
public void Should_be_able_to_merge_stale_object()
{
var obj = new Location { Address = new Address("1", "1", "1",
"1") };
Try to create a failing NUnit test and create a new issue (improvement) in
our JIRA.Thanks.

accessing properties of instances in invalid state when it is not needed.

My actual model is somewhat more complex than this:
public interface INum

}
public class Cat : Entity, INum

protected Cat() { }
public Cat(State state)
{
this.state = state;
}
public virtual State State { get { return state;
Mapping please.

I think that I understand. That is the case of merging a detached entity,

The fact is that the Merge need to read the state from DB but with its
result in the persistent class (not from DataReader).BTW I don't understand

Thanks Fabio, I will take a look at what a tuplizer is :), but I don't see
why NH needs to access the properties of a newly created object just to
overwrite them with the transient instance properties' values.

Ah.. sorry.. in Merge sure it access to the getter... sorryIf you need a
certain ctor you should implement your own tuplizer (I don't know where you
will find the State instance but it is another matter).

NH don't access to the getter during object creation. Try it.

Hi Fabio,
Num is a persistent property, and I have several entities that implement
INum; in this case Cat is delegating its actual implementation to its
private field "state".
I don't think that a nosetter access for Num would solve the problem because
the exception would be generated anyway (whe

That makes sense.

The answer to that question is that you don't. Think of NHibernate as a
synchronization tool, not a database persistence tool. It's trying to make
it so that the database is a form of "extended memory". You want both the

Thanks Jay,
So basically you are saying that what I do is correct, but your
solution is a shortcut as you are assigning the Person entity to the
Car entity within the Add() method.
Fair enough, but my initial question was, how can I do it without
having to specify the Person entity, i.e have the
ok i got it you mean adding the Car entity to my collection of cars in
Person. :)
But that's exactly what I do already :
myPerson.cars.add(new Car(1, myPerson))
myPerson.cars.add(new Car(2, myPerson))
sorry I should have included this code in my first post.
Yet I still get the problem.
O
cars.Add(car)
car.Person = this;
