I have a Form within a panel within a page. That form has one
FileUploadField and I based that form from the wicket-examples. The form
works well (of course, that's a copycat of the one from wicket-examples).
But now I have to use AjaxSubmitButton for that form, and now, It doesn't
work anymore. I don't have any clue
why I'm getting the following Exception when I click that AjaxSubmitButton.
