I think i understand it partly...Using NH you have something like
IList<Accreditation> employee.Accreditations as property .
The problem is, you have no easy possibility to take care of the
collection loading process...sorting, filtering etc. Sure, you may have
an order-by attribute in your mapping using a bag and you may have
filter definitions for the session etc. I'm aware that this is
a consequence of PI but i think it often introduces more problems
than necessary.
Anyway, since the sorting is in most cases a UI thing you can easylie
do something like
IList<Accreditation> pList = employee.Accreditations;
...
var pResult = from a in pList
order by a.ValidFrom
select a;
or simply
pResult = pList.OrderBy( a => e.ValidaFrom);
and then use pResult.ToList() for data binding;
