2 Possibilities:
First, via custom lifecycle, extend the standard elements in a way that
they refer to a form element and a first step collect those elements and
a second step at, form processing, processes those external elements
within the bounds of a form.
This applies to the apply request values and validation phases, or probably.
Second possibility:
But also you might get it easier (second option),
maybe you wont even need a second lifecycle if you can tackle the
problem via JSF2 system events on the controls themselves.
(you can set direct event listeners for various phases on the controls
so that they will be processed), this would be even faster since the
event handling mechanisms would do the bookkeeping for you which you in
the other case would have to do yourself.
This is probably the biggest problem with JSF and HTML5 (I did not know
this was possible, since I only follow the html 5 development via blogs
and articles), I would recommend also to raise a spec issue there
regarding this, so that we might, special handling for the official spec
so that no impl has to cook its own mechnanism in the long run.

Hi all,
I've been working on my GSOC project (prototyping currently). I want to
ask you something.
With HTML5, form elements does not have to be children of a form. Of
course, that is the preferred way, but you can set the "form" attribute
of the <input> and that <input> will be posted when the owner form is
submitted.[0]
This also applies to submit buttons, in a similar way. You can define
"form" attribute of the submit button, and it will submit the defined
form -not necessarily its parent- when it is clicked.[1]
So, I wonder if this can be applied in JSF side. AFAIK currently, a
commandButton needs to be under a <h:form>.
This is also about serverside component tree, and maybe state saving.
I couldn't set up much in my head.
What do you think? How can we use this new features? How to model them?
Thanks,
Ali
