IE8 and loading basemap issue

MatthewLofgren — Wed, 31 Jul 2013 18:06:58 GMT

In IE 8 (tried windows xp true IE 8 and windows 7 (IE9) IE8 browser/document mode)
About 1 out of every 20 page loads the base map doesn't load and the application stops.
I've cut my code down to just loading the basemap:
Also tried multiple doc types as well as removing the meta tags below.
Seems to be fine on all other browsers. Unfortunately IE8 is still important for us.

<!DOCTYPE html> <html> <head>         <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />     <meta http-equiv="X-UA-Compatible" content="IE=7, IE=9, IE=10" />     <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no" />         <link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.5/js/dojo/dijit/themes/tundra/tundra.css" />     <link rel="stylesheet" href="http://serverapi.arcgisonline.com/jsapi/arcgis/3.5/js/esri/css/esri.css" />         <script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/3.5" ></script>     <script type="text/javascript" >   var map;   require([    "esri/map",     "dojo/ready"    ], function (Map, ready) {    ready(function () {         initMap();      });        function initMap() {       map = new Map("mapPane", {        extent: new esri.geometry.Extent({"xmin":-11727455,"ymin":4861652,"xmax":-11706340,"ymax":4871512,"spatialReference":{"wkid":3857}}),      basemap: "streets"     });      }   });    </script>  </head> <body class="tundra" style="background-color: White;">        <div id="mapPane" >                 </div>  </body> </html>

Also, before I stripped down my code, I had an error handler for the basemap and it would return
"Code undefined : Unexpected call to method or property access." but no file or line #.
Anyone have a clue?

Thanks!

Not sure if its the same problem but I had issues with IE8 and TOC not loading. I delayed the startup for the TOC by half a second and it's been working great ever since.

setTimeout(function () {         CreateAndDrawTOC();     }, 500);

Do you get the same problem with this page? (View source here.)

Not sure why this is, but sometimes I get errors in Firebug that don't have additional info or the stack. Generally when this happens I can use Developer Tools in Chrome to get more info.

Yep. Took a bit longer. ~30 refreshes but same result.

Also, happens here http://developers.arcgis.com/en/javascript/samples/map_infowindow/

Takes a few refreshes to see it.

This doesn't happen in 3.0 but I'd like to upgrade to use some new features.

Wrapping the initMap() function with the minimum setTimeout delay of 4ms did seem to work.

setTimeout(function () {   
      initMap();
     }, 4);

ready function firing too quickly for ie8?

Thanks everyone.
