Thanks for the quick reply David!  It looks like the Undo() method is the "right" way to do what I want to accomplish anyway.]]> Mon, 27 Aug 2007 14:32:12 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=385&PID=986#986 PropertyChanged not firing for new entities? : The entity.AddToManager method... http://www.ideablade.com/forum/forum_posts.asp?TID=385&PID=985#985 Author: davidklitzke

The entity.AddToManager method should typically get called within a few instructions of calling the CreateEntity method.  After an entity is created, it is in a detached state, and, strictly speaking, is  not a "real entity".  Therefore, please do not try to bind an entity when it is in a detached state.]]> Mon, 27 Aug 2007 14:25:46 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=385&PID=985#985 PropertyChanged not firing for new entities? : If I create a new entity by calling... http://www.ideablade.com/forum/forum_posts.asp?TID=385&PID=984#984 Author: joshpainter

If I create a new entity by calling the PersistenceManager.CreateEntity<T> method, and then bind that new entity to the UI without first calling entity.AddToManager(), it doesn't seem like the PropertyChanged events are firing to update the bound controls.  Is this by design or is it a bug?
 
Thanks!
