hi Martin
I tried your code but had issues with it (bound to jetty + to instances
of IOnChangeListener)).
However, it made me look directly into
AjaxFormComponentUpdatingBehavior.onEvent(..), where I ended keeping
only formComponent.inputChanged(); .
But then other issues started to rise: first of all how to call
convertInput() in FormComponent, which is protected. Then, later on, my
use case requires that I "setInput" on some CheckBoxes, which isn't
doable neither.
In the end, it feels like Wicket isn't thought for allowing to play
directly with component's input, requiring rather to go through models
only. This is, I guess, a compromise which makes sense overall (the
risks of breaking the form process could be quite high I assume).
Regarding my needs, it means, AFAIK, that I'll have to use a copy on my
model's object in my current form, copying it back when the form is
successfully submitted.
thanks for your help in understanding that :)
cheers

there is ajaxformsubmitting behavior which will update the entire form

thanks
however, that's not exactly my need, being just recording the user input
(not to loose it) without validating. Is there no way around, like a hook
from Ajax to act only on some component internal state ?
My use case being the following:
The use case for it is a ListView with reuseItems(true) which loses in
transit state. In more details, it means the user writes something in one
of
the listitem's textfield, then click on "add new item" => I want the
textfield's state to be known and preserved, whereas the whole form
shouldn't be submitted yet.
which approach would you recommend ?
thanks again
