If T5 already has the ability to persist fields into a form, then how to do
you retain those fields during a redirect? The URL is not long enough to
serialize every hidden field. So you'd be forced to store it in the session,
which breaks the scenario of multiple browser windows in the same session.

Subject: Re: T5: Redirect after form submit - concerns
T5 has the ability to to persist field properties onto the client (as
zipped/based64) automatically. These show up as hidden form fields or
extra query parameters. Not implemented yet is the ability to "scope"
the data to only hidden form fields (but leave normal links unchanged)
... the API is present, there just isn't an implementation yet.

We are in the process of evaluating T5 and other frameworks to upgrade
our existing trading applications from T3. We extensively use objects
serialized to hidden fields (zipped and base64 encoded) to manage state
because we absolutely have to support multiple browser windows in the
same session. However, T5's redirect after form submit throws a wrench in
the design since it forces the uses of session to store the data which
fails with multiple browsers and creates unnecessary traffic in a
clustered deployment. Why is this redirect necessary and is there a way
of overriding/turning it off? If there is no way around it, T5 will not
be an option for us to upgrade to. So I'm hoping to arrive at a solution.
