You're going to have trouble with that approach I think if you have
two instances of the same page up for the same session because the
persistent properties are linked to session/page, not session/page/instance.
So if you bring up:
Edit Invoice 1 -> Persist 1
Edit Invoice 2 -> Persist 2
Submit Invoice 1 -> Bootstrap 2 (the most recent persist) -> we just
overwrote invoce 2 with invoice 1.
