Scenario: An existing product line, adding new traffic line to that
product line. Attaching the children (traffic lines) to the existing
product line through helper:
ProductLine 1:M TrafficLine
newTrafficLine.ProductLine = this; //associating the child with the
parent
Hello all,
new to the list, hope I'll be able to contribute as well :)
Before I begin, here's a bit of background: I'm working on a library
cataloguing application using NHibernate + Spring.Net (the latest
versions for both) strictly for educational reasons...
The exception I've mentioned is

Why does it not perform the select to retrieve the newly generated id
when I SaveOrUpdate on the parent (product line)?
Because NH delay the DB access as late as possible.If you really need the ID
and you want force the DB access you have two choice:
1)
Fabio, thank you very much for your reply.
1. Do you know why it does return the id when you perform a SAVE
directly on the child (_traffcLineDao.Save(newTrafficLine);)?
2. Why does it work differently than the SaveOrUpdate on the parent?
3. Is there a post somewhere that explains this i depth

Yes. you are explicit persisting an entity avoiding automatic cascade.

Hi Fabio, to answer your question and to clarify my answer:
I don't understand what you are talking about. If the ID have no meaning why
your user must see it ?
If you need to know which element is selected you may use the index of the
list, if you are using ISet you should implement an

Yes Kris, the final is not out yet :-(
Just to get back to my topic, would all here agree that in order to
get the id (by the way Persist() does not perform a insert and select
to get the newly generated id) for an newly added child, regardless
for the reason why, that I need to call Save on

Hi,
I would like to filter the data that is being retrieved by NH from the
database. I have a class projecttype, which holds a collection of
projectsteps. But I only want to load those steps that are active.
So I figured I could define a filter in the mapping somewhere, so that
