		/// Perform any property value substitution that is necessary
		/// (interceptor callback, version initialization...) 
		/// </summary>
		/// <param name="entity">The entity </param>

		/// <param name="persister">The entity persister </param>

			//keep the existing version number in the case of replicate!
			if (persister.IsVersioned)
