Let's say I have a Parent entity and a Child entity but they are mapped
with no cascade save of the Child entities, and I forget to call Save() for
the Child entity like so:
using(var s = sf.OpenSession())
using(var t = s.BeginTransaction()) {
var newParent = new Parent() {Name = "NewParent"};
var newChild = new Child() {Name = "NewChild", Age = 10};
newParent.AddChild(newChild);
s.Save(newParent);
t.Commit();
}
This will throw an exception similar to this:
*"object references an unsaved transient instance - save the transient
instance before flushing or set cascade action for the property to
something that would make it autosave. Type: NHibernateLab.Models.Child,
Entity: NHibernateLab.Models.Child"*
All of this is all fine. But now, let's pretend there are lots of different
types of entities that have a one-many relationship with the child entity
types, how can I find out what type of entity it is that we're trying to
save that has a reference to the transient Child entity that causes the
exception? Is this possible? Can I dig through the session's sessionimpl
somehow to find out?
