It depends on what you are doing with entity B.
If you are not modifying any B objects, then you don't need to do
anything because only updated/inserted/deleted objects in the editing
context will get committed to the database.
If you are modifying A and B objects, then you can't just commit A
changes because both A and B objects must be part of the same editing
context. If this is what you need to do, then i think you might to
reconsider your model.
Basically, what gets committed is determined by the editing context you
call saveChanges() on. This is what determines the DB transaction.

Hi,
I have some instances of entity A that are not functionnal without
related instances of entity B.
But in some circumstances, I need to save only the instances of object A.
What is the best strategy to acheive this?
Thanks.
