My initial thought for dealing with this was simply to not insert the order and associated lineitems into the db context until after the process is complete. The problem with this is that it violates one of the rules I've read about. That is, that you should insert objects into the context before any manipulation of those objects.
Inserting in a context is not the same as inserting into the DB. The context is a sandbox, you can play all you want on it (well, as long as you don't hit any EOF bug, but that only happens to me and on very weird stuff!). When you are happy with your work, saveChanges() and only then the data will be recorded/updated/deleted on the database.
So the elegant solution is simple: use EOF as it was meant to be used! :) It's already elegant enough! :)
Mind the back button, you don't want to create two order objects if the user starting going back and forward.
