In my sample I'm putting the Graphics into the dataProvider. You're creating new Objects with a data property that points to the Graphic, so in your change handler try: var extent2:Extent = Graphic(cmb.selectedItem.data).geometry.extent; ... View more

What is your <layer> tag? Is your Viewer url on the same host and domain as your ArcGIS Server? If not, you'll need to add a crossdomain.xml file to your ArcGIS Server. Also, you can use a tool like HttpFox to see what requests are being make and if any of them are failing. ... View more
