This is a very personal opinion but...
If I got you correctly you have a lot of sp:s with business logic and now you
want to put the business logic into queries using a nhib? My suggestion is -
don't do it. If you prefer seeing a db as a place for storing data _and_ a
place for business logic
from A a inner join a.B b where
or
CreateCriteria(typeof(A)).CreateAlias(B,b, JoinType.InnerJoin)
Why is b's data returned in the result set/part of the select clause (if fetch
or SetFetchMode isn't used)? I'm feel I'm missing something obvious here...

Criteria
* Nicer api if you want to build the query at runtime.
* Can query non mapped types
HQL
* Can be pre parsed
* Easier (?) syntax for dba:s
* Collection stuff (elements, all, minIndex, maxIndex etc) are better supported
in HQL afaik
(Certainly there are more diffs, but these were the
you can not make cartesian products with criteria.
?
aCartesianProduct = s.CreateCriteria(typeof(Foo))
.SetFetchMode(ACollection, FetchMode.Join)
.SetFetchMode(BCollection, FetchMode.Join)
.SetFetchMode(CCollection, FetchMode.Join)
.SetFetchMode(DCollection, FetchMode.Join)
.ListFoo();
joins from Foo to everywhere.
all with an ON clause on the join.
SELECT ...
FROM Table1, Table2-- (no join)
-- (no rel restricting WHERE)
this can be done in HQL, and afaik not in Criteria

If your real world case is more complex than your example (?), I would consider
impl state pattern rather than your enum.
giving the object an initialization state
IIRC - I've seen some example at nhforge how to use a parameterized ctor, but
if you want to keep your design, it's seems a lot
I don't know what you're trying to accomplish but...
Each isession is an identity map. If you read an entity in another session, you
will have two different instances.

It's used by SchemaExport. It may also be used by you (or other fw) if you need
this info for your own purposes.
AFAIK, nh does not use this info for any validation/truncation at all. How
should this be done in some general way? Truncated? Throw ex? Trim the string?
etc etc

Hi
AFAIK session's timestamp isn't ever changed. Why isn't it updated when it
commits a transaction? That would potentially give more cache hits if its life
time spans more than one transaction. It's not a big deal at all, I'm more
curious _why_ - it's obviously something that I miss. In what
