[Laszlo-dev] Help fixing LPP-5926

Mon May 5 14:23:37 PDT 2008

This is definitely an IE6/7 issue. The following javascript code 
fails in IE6/7 if I call apply() when the argument is a function. 
Calling it with explicit arguments works.

<body>
   <script>
     function setTimeout_broken() {
       window.setTimeout.apply(null, arguments);
     }
     function setTimeout_works(f, msec) {
       window.setTimeout(f, msec);
     }

     function test () {
       var f = function () {
         alert('hello');
       };
       setTimeout_broken(f, 1000);
     }

     test();

   </script>
</body>
