The PersistenceManager has a (client-side) Saving event that you can handle to inspect (and change) the collection of Entities being submitted for a save.  The handler gets an EntitySavingEventArgs parameter that has an Entities property which is an IList<Entity> and contains all the Entities being submitted. Simply remove the entities you don't want submitted from that list.

I have had reason to create a business entity class backed by a view that cannot be updated, and  I would like to allow entities of this class to be editable in my application.  However, I want to prevent these view-backed entities being saved to the database, since to attempt this will cause a database error.

Is there any way to mark an entity class or a set of objects as being not-for-saving so that the Persistence Manager knows not to attempt to save them to the database?  Thanks in advance for any help anyone might have!
