I've resolved the issue by removing the "not-null" attribute from my
audit fields. I could add this constraint at the database level after
NH generates the tables with no ill effects, so I think this is
probably the best solution.
Thanks for suggestions!

I think you need to initialize events differently for collections.
Did you try InitializeCollectionEvent to tie thecollect to the event
source.
Anybody else have any help?

Thanks for the suggestion. I tried hooking in listeners for
IPreCollectionRecreateEventListener and
IPreCollectionUpdateEventListener but neither fire before the
validation check on the child's audit properties. My unit test
that's failing essentially does the following:
Parent=CreateParent("Parent1")
Parent.Children.Add(CreateChild("Child1"))
Parent.Children.Add(CreateChild("Child2"))
Session.SaveOrUpdate(Parent)
(Note that I can create or update the childless parent with no
persistence issues, and both pre-insert and pre-update events fire
and set audit information correctly.)
On the SaveOrUpdate call, OnPreInsert() is raised for the Parent
object, but neither of the collection listeners are raised before
the validation check throws an error on Child1. Either way, I think
this is probably not the approach I want to take because if the save
is done on the child object and the parent is dirty, I want to
update audit info on the parent before it is persisted.
I may have to resort to setting the audit information in the
business layer, but it seems like something I should be able to deal
with in the persistence layer (I've always done it in my stored
procs in past apps) without having to jump through too many hoops.
