First of all, I'd like to thank everyone involved in creating and developing the toolkit. You made web development fun again.
I've borrowed from the flightViewer example to create one using the xmlHttpRequest object. I've also included the css file needed for the flightViewer example to properly display icons. The css file goes in the js/dwt/config/img/hiRes folder, DataController.js goes in dataViewer/controller, and the other two in dataViewer.
You may have to edit the html file depending on the location of your toolkit files. If the icons are not showing up in the flightInfo example, it's because the path specified in background-img:url is relative to the css file, not the page requested.
Keep up the good work.
