I see that FileUpload is available now via Ajax
(https://issues.apache.org/jira/browse/WICKET-2420). However, is it possible
to upload from a ModalWindow via Ajax?
In my AjaxButton, my FileUpload object is not being set. I am also not seeing
an IFrame in the Wicket Debug
I have attached my code if that may help.
Thanks
