Hi, Thanks for sharing your solution! IMO this is a special case that is not that common to be in Wicket core. It also assumes that Form#setOutputMarkupId(true) has been called.
What about marking the form as multipart from the beginning (Form.setMultipart(true)) ? I think it should work even i there are no FileUploadField fields in it.
