This was so much fun ;)
public class SelectAllChoice extends CheckBox implements IHeaderContributor {
/**
* @param id
* @param abstractChoice

super(id);
add(WicketUtils.getAttribute("onchange", "if (this.checked) {
$('#" + abstractChoice.getMarkupId() + " *').attr('selected',
'selected'); } else { $('#" + abstractChoice.getMarkupId() + "
*').attr('selected', ''); $('#" + abstractChoice.getMarkupId() +
"').trigger('change'); } $('#" + abstractChoice.getMarkupId() +
"').trigger('change'); return false;"));
}
