The problem is that wicket-ajax doesn't support multipart forms.

I'm attempting to upload a file using a form with an AjaxSubmitButton.
Ideally, I'd like to swap out a panel once the form is submitted, but
I'm not getting that far. When I submit the form, I'm getting the
following exception:

I've called 'form.setMultiPart(true)' and the form submits fine without
the AjaxSubmitButton. Any suggestions?
