In any case, you should use a nullable enum property instead of a NONE
value.
My impression is that you are designing your domain based on display
concerns.

My suggestion is that you host the project on Google Code or SourceForge (I
prefer the former), with a reasonable license (NH itself uses LGPL). Good

If you just want to do this, you really don't need NHibernate. Just do a
traversal of the properties using reflection.
Pusedo code would looks something like:
create a queue
enqueue the type of the root entityType
while the queue is not empty
- get all the properties and their property type
-
Unfortunatly there were no results.
It runs for 5 minutes, outputs everthing to the console and applies
nothing.

Well the console part is because you have the first paramater (script) set
to true. Not sure why it isnt outputting though. Does SchemaExport work to
create the schema initially with that same connection string?

You could set the access to use a private field and not put a setter on the
property. ReadOnly means that any update wont be written out, but it still
requires a setter of some sort so NHibernate can initialize it.

Yes, I can. But why should I use reflection when NHibernate already

We use one (read-only) session which we disconnect as soon as we
retrieve the data from the database. The data retrieved, often has
lazy-loaded properties which are not initialized yet.
When we try to access the properties, the following exception gets

It seems that the option you're talking about (called in hibernate:

nHibernate. A piece of code from nhibernate source:

Not sure about FNH, but using hbm mappings you don't need a setter if you
declare a property with access=readonly.
NH will keep track of the DB value, do dirty checks with it and issue the
appropriate updates to the DB.

I think the simplest way to implement this (regardless of whether it's right
thing or what reasons make you ask for it) is to map a nullable enum FIELD,
and make a property (that is NOT mapped in NH), which reads and writes the
field value.
something like:
