Wow, that's a fairly creative way to remove an item from a list. Try
just using one of the Remove() methods on the list. Something like
the following:
public virtual void RemoveDetail(ProductDetail productDetail)
{
// assuming productDetail is an object from the list, then
this is the simplest...
//productDetail.Product = nothing;
//ProductDetails.Remove( product );
// otherwise
var item = (from p in ProductDetails where p.Id ==
productDetail.Id select p).FirstOrDefault();
if(item!=null)
{
item.Product = null;
ProductDetails.Remove( item );
}
}
you can't just create a new ProductDetails collection since NH may
be tracking the old one using a proxy class.
