You need to call setOutputMarkupId( true ); on the object you're adding to
the AjaxTarget.
ie: If your Feedback panel has the output markup id set to true (you can
see it in the HTML as <... id="someWicketGeneratedId" ... \> and you add
the parent of that Feedback panel ot the target you will get an error.
