If sortable lists used twice on one page and the first list contains items & the
second doesn't $selectarea_selected_str still contains the values of the first
when second sortable list is generated.

Added the else to the end of the if statement in CGExtensions.module.php line
693+:

        if( !empty($selected) ) {
            $sel = explode(',',$selected);
            $tmp = array();
            foreach($sel as $theid) {
if( array_key_exists($theid,$items) ) $tmp[$theid] =
$items[$theid];
            }
            $smarty->assign('selectarea_selected_str',$selected);
            $smarty->assign('selectarea_selected',$tmp);
        } else {
            $smarty->assign('selectarea_selected_str','');
            $smarty->assign('selectarea_selected',array() );
        }
