Hi Matej, Thanks for the answer.
I have an AjaxSubmitLink both for opening and closing the modal window. Should that make any trouble? In both cases i have data to persist, so it must be a .*Submit.* component. Also, my problem happens when closing the window, not when opening it. I summarize it again: -the browser sends an ajax call with the values in the modal window -but on wicket side the main form of the page is the one that takes charge -the components on the page then receive the new input, but there's actually nothing coming from the browser for them -some components (text components) handle it well, some not (checkbox, dropdownchoice). -the misbehaving component get a rawinput of null instead of NO_RAW_INPUT, which then produces the side effect that the component does not get the value from the model on rendering. Please see the doubts section at the end of the original e-mail.
