Hello Vincent,

Here is a litle example :

    class MyEntityServerSaveManager : EntityServerSaveInterceptor      {        protected override bool ExecuteSave()        {             foreach (var entity in EntityManager.FindEntities(EntityState.Modified).OfType<MyEntity>())            {

                var oldValue = (string)EntityAspect.Wrap(entity).GetValue("MyStringProperty", EntityVersion.Original);
                var newValue = entity.MyStringProperty;

                if (oldValue != newValue)

                {

                //...                }            }                        return base.ExecuteSave();        }     }
