KML layer extents

Question

I want to set the Extent of the map automatically to focus on the layer shown by the kml, with an appropriate zoom. I am using the following snippet, which is specified in here: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi_start.htm#jsapi/kmllayer.htm var kmlExtent, layers = kml.getLayers(); dojo.forEach(layers, function(lyr) { if ( lyr.graphics && lyr.graphics.length > 0 ) { var lyrExtent = esri.geometry.geographicToWebMercator( esri.graphicsExtent(lyr.graphics) ); if ( globals.kmlExtent ) { kmlExtent = kmlExtent.union(lyrExtent); } else { kmlExtent = lyrExtent; } }); map.setExtent(kmlExtent); However it does not seems to work, the element seems to have no layers. This is my complete code: [HTML]

[/HTML] Can anyone help me with this? :S Thank you.

We have used similar code to display the kml layer.It works in a simple html.Our requirement is to show the KML map in microstrategy.According to me I should be modifying the esrimap.js of esrimapviewer.js or other esri related js files.

Please let me where should i integrate the code to get the kml layer displayed in micro strategy.

I think the presence of a folder in the KML file is red herring. The problem appears to be that one of the KML layers has a single point which does not result in a valid extent. Try this:

Display KML Using a KMLLayer

The map displays a simple KML file that was created using Google Earth and is hosted on an Esri server. Symbology and attributes are honored.

Everything was working perfectly with a linestring or a placemark. However when the kml contains an Folder element with both, I am getting an exception: "TypeError: Cannot call method 'toJson' of undefined".

This is the html: http://dl.dropbox.com/u/21472423/esri/kml.html 
And this is the kml with Folder element: http://dl.dropbox.com/u/21472423/esri/kml-folder.kml (The syntax is correct).

Does anyone know how to do this?

Thank you.
