There is a link already. He got orders from customer (from o in *c*.Orders,

I don't think you can, but give it a try anyway.
IF it doesn't work maybe you can do it the other way around. Query on orders
and then select o.Customer.

What I need is a default mapping from System.String to AnsiString. So I
could use both if I want. In the SqlDriver I can replace string with
ansistring but if I do so I can't use string anymore.

So for example I have 2 columns:

[EventId] [int] NOT NULL,
first is primary key, second should be auto incremented (generator
class=increment/).
And most desired it should be done in single

The event handlers are just a mechanism. The underlying idea is that:
a) all applications need to decide on a strategy for handling the
NHibernate session (and transactions).
b for many applications it makes sense to divide the work into units of work.

You have to map that enum using int instead string... perhaps.

I haven't used SM, but it appears to be OK. I prefer to manage

this may be a byproduct of using Windsor.

The default is the opposite and you can't change it on the compiled version.
But since NH is open source, you can modify lines 197 and 198 in
src/NHibernateType/TypeFactory.cs to use AnsiString instead of String.
Or you can leave it as-is and pay a third-world contractor 50 bucks to

Its not simply that your object model is not correct but that things
are just not modeled the way you have approached it. Generally when
you create an object it does not change its class. Ever.
What you are trying to do is have a object of a class that can be
