I found another way to make this work too. It turns out the solution was in
the LivePipe system, since it provides an "afterOpen" option to any object
you create, which is just like Prototype's "onComplete":

     57                         var w = new
     58                                 className: 'window_modal',
     59                                 closeOnClick: window_close,
     60                                 overlayOpacity: 0.75,
     61                                 fade: true,
     62                                 afterOpen: function(){
     64                                 }
     65                         },options || {}));
