Hello
This is rare situation but is that bug or feature?
I have detached object with lazy details something like
public class Ent
{
public virtual ISet<XDetails> Details
{
get
{
return (_details ?? (_details = new HashSet<XDetails>()));
}
protected set { _lines = value; }
}
private ISet<XDetails> _details;
Nhib 3.3mapped to access _details directly, not by Details property
Instance of Ent exists in DB and have no details
I need to update instance by data coming from GUI;
no detail was created in GUI
as result before calling Merge ent._details == null
when flushing session -> exception "A collection with
cascade="all-delete-orphan" was no longer referenced ....."
If before calling merge, initialize _details with empty collection (access
property for example) - all is OK.
During merge Nhib instantiate new instance of Ent, load it from DB, and
then copies property values from given obj to newly loaded.
During instantiation Nhib initialize _details collection by it's internal
Persistent coll wrapper.
During copy process it copies _details (==null) to newly instantiated
object.
So empt collection created during instantiation & load become not
referenced....and this is source of exception.
Is that bug or not?
