Hi Martin,
thanks for your reply, it definitely made my day! I had to tweak the
snippet a little, because Wicket.Form.serialize() returns an array of
objects that does not really work out for the AJAX request. So I changed
the value expression into Wicket.$(id).value and that worked perfectly.
Thanks a lot!
