Problem: When adding a new row using the RadGridView control, when the row is actually added to the control (after the initial editing in the new row area), two rows actually appear and they both appear to be bound to the same object.

The attached example is in vb, but I believe I did the same thing in c#.  Also, I believe the same occurs whether you are using .NET 3.5 or .NET 4.

This is not a problem using a standard datagridview.  It exists with RadGridView.  As such, I thought the problem was limited to RadGridView and not OpenAccess, but I am not really sure which is the culprit.  

My sample uses the Cars table copied from the SofiaCarRental example.

I have used the older Reverse Mapped style OA project.  I have seen this behavior since 2010.Q3, but not sure when it really started.
