Hi,


I'm new to NHibernate.
How can I use BindingList(Of T) instead of IList(Of T) in my application?

When I have my property declared as IList(Of T) everything works fine, but when I use BindingList(Of T) I get this error: {"Invalid mapping information specified for type Ghost.clsFournisseur, check your mapping file for property type mismatches"}

with Innerexception:
{"Unable to cast object of type 'NHibernate.Collection.Generic.PersistentGenericBag`1[Ghost.clsPersonne]' to type 'System.ComponentModel.BindingList`1[Ghost.clsPersonne]'."}


Thanks a lot in advance,

Pieter

Name and version of the database you are using: SQL 2005 SP1

You'd have to write a user collection type for that. See IUserCollectionType interface documentation.
