I think your problem is really with the redirect-after-post paradigm.

Try @Persist("flash"). When you read the value it's removed from the
session until you store it again. This generally solves the problem.
The one place where you might it a snag is if you redirect to a
different page after posting the form. In that case the value will
remain, you can call
ComponentResources#discardPersistentFieldChanges() if you know you're
not going to be redirecting to another page.
