the problem is file uploading with ajax - that's just not possible
(restriction of the http protocol as far as I remember), however you can
'simulate' using some approaches, e.g. a hidden iframe where you post your
file to. 
that topic has been discussed many times, just search the list - if i
remember correctly there's already a component for that somewhere in
wicketstuff ...

Michael
