can you not just create a new ContactVO with your form control values when the user goes to save their changes, and, depending on the result from the server, either set your form controls back to the model (you'll have to assign them manually as binding won't fire if the values don't change) if the save fails or set your model to the newcontact values if the save succeeds?
