I have a winForms app with MVP pattern, and i don't how to use
Nhibernate with lazy loading in this pattern. Currently I'm using
eager fetching with LOTS of left joins.
So for example how manage ISession with lazy loading in classic MVP
situation when you have app showing list (DataGridVIew) of
BuisnessObjects and a Form to add\edit this BuisnessObject?
In my current implementation i'm doing something like this:
in my Model:
public IList<BuisnessObject> BuisnessObjectGetAll()
{
using (ISession ses = SessionFactory.OpenSession())
{
IQuery query = ses.CreateQuery("from BuisnessObject as
obj");
return query.List<BuisnessObject>();
}
}
In my BuisnessObjectList Presenter:
View.Items = Model.BuisnessObjectGetAll();
and in my View implementation i bind Items to DataGridView
As you may guess with lazy loading a get lots of exceptions because
ISession is closed after i return Objects from my Model. So i want to
know how to manage ISession in this situation?
