It is exactly the same is i was talking about
Only i am rendering the form directly again, But that doesn't have to be
the case ofcourse.
I want to hold state in the form without that it goes anywhere else
Same as you want, just keep the input of the form but don't do anything
with it except rendering it again
(at one point in time)

I don't think we are talking about the same thing here. Take my wizard
example:
A user is on page 4 of the wizard. They fill out the form half way, relize
they forgot something on page 3 and click the back button. At that point
what we want to do is capture whatever the state of the form on page 4 was
at that point because later when they click next on page 3 we want to show
the form on page 4 just how they left it. The back button does a form submit
with the default form processing turned off.
So to make the above work all you need is something like this :
FormState state=Form.getState(); <=== this creates a state object that
stores all formcomponent.invalidinput fields
And later page 4 can do this:
FormState state=wizard.getFormState(4);
If (state!=null) form.setState(state); <== this would fill in the
invalidinput properties of the form components controls.

Subject: Re: [Wicket-develop] More button talk.
this discussion starts to boil down to keeping state in a form which
will be used in a render phase again
without updating it to the models or do anything with it.
This will be build (i think by me) as the first thing after we finalized
1.1
Because this is a thing we really need (there is a bug report open for
this)
We need to be able to do things on in the browser like having a
selection change event on a select box
but when that happens we can't loose the form data a user already has
filled in.
Currently we loose the data users put in because now we just generate a
link with the onchange
but the onchange should be a post but only to hold the submit values at
someplace in the form
but do nothing with it and call the interface method of the onchange
event.
I don't get the binding but not validation completely
When is the validation then be done?
Do you have a form that goes over multiply pages? And only when you have
reached the final page
the validation can be done?
If that is the case then the form should hold its values are long as
possible. (i can use the invalid_input field for that)
and only when you call validate it will be done.
