a much simplified version:
<div wicket:id="logData">log contents</div>
<div wicket:id="nextLog">next log call</div>
no panel needed. add self-updating behavior to next log call and in
the callback also add
target.appendjavascript( "$('#logdata).append($('#nextlog).content());
$('#nextlog').remove(); $('#logdata).insertafter($('<div
id='nextlog'>));" )
im paraphrasing jquery here, but the is that you repaint the nextog
div and add javascript that after the repaint you move its contents to
the logdata div, and then empty the nextlog div. of course the nextlog
div should be hidden via css....
