This is the way I've set up an application (not in the SFV framework) to read in a configuration file. The application is a framework where I'm showing the data for several different projects and the XML contains all the parameters for each project, including map service and query URLs. I pass in a parameter in the main URL for the specific project: http://ccma.nos.noaa.gov/explorer/biomapper/biomapper.html?id=JobosBay http://ccma.nos.noaa.gov/explorer/biomapper/biomapper.html?id=StJohn This is the code for the Flex application to read in the XML file private var xmlParameters:XML;    private var xmlProjectParameters:XMLList; private function init():void {     var xmlLoader:URLLoader = new URLLoader();     xmlLoader.addEventListener(Event.COMPLETE,init_onComplete);     xmlLoader.addEventListener(IOErrorEvent.IO_ERROR,fail);     xmlLoader.load(new URLRequest("parameters.xml")); } private function fail(event:Event) {     Alert.show("Fail"); } private function init_onComplete(event:Event):void {     var params:Object;         try     {         var loader:URLLoader = URLLoader(event.target);         xmlParameters = new XML(loader.data);                 params = getURLParameters();         if (params["id"])         {             input = params.id         }         else         {             Alert.show("Parameter search failed");             return;         }                     xmlProjectParameters = xmlParameters.project.(@urlinput==input);         var bm:IBrowserManager = BrowserManager.getInstance();         bm.init();         bm.setTitle(xmlProjectParameters.@id + " BIOMapper");          serverName = xmlProjectParameters.service;         projectTitle = xmlProjectParameters.projectname.@name;         if (!(xmlProjectParameters.datalayers.dive==undefined))         {             diveQueryTask.url = serverName + xmlProjectParameters.datalayers.dive.@url + "/MapServer/" + xmlProjectParameters.datalayers.dive.@layer; etc... } private function getURLParameters():Object {     var result:URLVariables = new URLVariables();         try     {         if (ExternalInterface.available)         {             var search:String = ExternalInterface.call("location.search.substring", 1);             if (search && search.length > 0)             {                 result.decode(search);             }         }     }     catch (error:Error)     {         Alert.show(error.toString());     }         return result; } And this is the code for the XML file <?xml version="1.0" encoding="utf-8"?> <projects>   <project id="Jobos Bay" urlinput="JobosBay">     <projectname name ="Jobos Bay, PR" pdftitle="Jobos Bay, PR: Shallow-water Benthic Habitats" url="http://ccma.nos.noaa.gov/ecosystems/coralreef/ceap/"/>     <service>http://egisws02.nos.noaa.gov/ArcGIS/rest/services/biomapper/Jobos_</service>     <datalayers>       <dive layer="0" url="Dynamic" site_id="Site_ID" videoname="Site_ID" assessment="Assessment" photocount="PhotoCount" symbol="Symbol" legendurl="http://ccma.nos.noaa.gov/explorer/biomapper/jobosbay/images/Dives.png" legendheight="53">       </dive>     </datalayers> etc   </project>     <project id="St. John" urlinput="StJohn">     <projectname name="St. John, U.S. Virgin Islands" pdftitle="U.S. Virgin Islands (St. John): Shallow- and Moderate-Depth Benthic Habitats" url="http://ccma.nos.noaa.gov/ecosystems/coralreef/benthic/"/>     <service>http://egisws02.nos.noaa.gov/ArcGIS/rest/services/biomapper/StJ_</service>     <datalayers>       <dive layer="13" url="all" site_id="SITE_ID" videoname="VIDEONAME" assessment="ASSESSMENT" photocount="PHOTOCOUNT" symbol="SYMBOL" legendurl="http://ccma.nos.noaa.gov/explorer/biomapper/stjohn/images/Dives.png" legendheight="103">       </dive> etc.   </project> </projects> ...

You don't need to make a call to a geometry service if you are projecting lat/long to or from Web Mercator. The WebMercatorUtil class does this for you.

In my application, I've taken the results of the Identify and pushed it into an array, then set the DataGrid's dataProvider to that array. This is part of a larger code for an application that takes the IdentifyResults from all the visible layers and puts the results from each layer into a separate tab in an InfoWindow.                 identifyTask.execute(identifyParams, new AsyncResponder(resultFunction, faultFunction, clickGraphic));                 function resultFunction(results:Array, clickGraphic:Graphic):void                 {                     if (results && results.length > 0)                     {                         var resultsArray:Array = [];                         var newDG:DataGrid = new DataGrid;                         resultsArray.push(result.feature.attributes);                         newDG = new DataGrid;                         newDG.dataProvider = resultsArray;                     }                 } In reading your post, I was seeing DataGrid instead of DataGroup. However, the dataProvider expects an IList, which could be an ArrayCollection, ArrayList, and       XMLListCollection, so you should add your graphic to an array. ... View more

Here's some code in one of my applications that will populate a datagrid from a map click, putting it into a tab navigator in an InfoWindow. The portion of the code that is commented out allows you to get back the results from multiple visible layers in your layer, which are put into separate tabs. The listeners that are added allow you to highlight the features on the map when you click or roll over the entries in the datagrid.             protected function MainMap_mapClickHandler(event:MapMouseEvent):void             {                 var identifyParams:IdentifyParameters = new IdentifyParameters();
