Thanks for the direction! I'll look into it.
Would you happen to know why the aspect I'm introducing with the line
@event.Entity = Factory.GetProxy();
gets stripped?

Use composition instead of inheritance.

I have the following simple class structure, simplified for post:

The problem I am facing is when I pass in the person and assign all
the values to this object including the ID, it wants to update

Do I need to explicity load hibernate.cfg.xml? For some reason, it
looks like your basic test fixture calls configure *after* compiling

To apply Aspect you should write your own IProxyFactory or better more your
own NHibernate.ByteCode.XYZWith the ByteCode you have full control about
anything is related to proxy generation.
In NH2.1.0 (the trunk) you have two implementation : LinFu, Castle.
Another partial example is here:

I do have additional optional behavior, that has varying
implementations, that needs to be apart of some classes some of the
time. And some of those classes I control and others I don't. Of the
ones I don't I can reasonably count on the interface staying the same.

Hi,
Sorry, now I realize *I can´t do what I planned in .NET*.
I was trying to find a way to break a Domain Class so that it doesn´t have
to hold a reference to all kinds of Classes. Initially I thought I could do
that with Extension Methods but I don´t have a way to store the association
values
I can't send actual classes and tables, but let's try simple example:
abstract class BusinessObject
{
}
class ConcreteObject1 : BusinessObject
{
}
class ConcreteObject2 : BusinessObject
{
}
Additionaly thera are many ohter classes inherited from
ConcreteObject1 as well as ConcretObject2. Excep

Then again probably not. So close and yet so far due a technical

I guess I need to implement some kind of set of objects that are to be
locked later at commit time (LockMode.Read).
This set will be populated by the Proxy that I've been talking about.

Sorry but to create a mapping i must know, at least, 2 things: the class and

The reason I ask is becouse I think this would force a version check
at commit time on that object. That is all I need to make this work :)

Yes, I know syntax of "mixing table per class hierarchy with table per
subclass".
But I require one SHALLOW (used as read-onlu) hierarchy used and several distinct hierarchy used "mixing table per class
hierarchy with table per subclass" with base db tables from first one
hierarchy.

The strategy "mixing table per class hierarchy with table per subclass" is a
special and specific feature of Hibernate and NHibernate.The implementation

Your mapping is wrong...You should define the ClassB inside the
node and no out-side as an independent class.

I imagine it shouldn't be an issue to persist the class in diff DBs with
separate configs and session factories if that's what you mean.

You CAN'T use mapping more than one class to the same
table.
If you want use only one table you must use or a trick like this
