It works in Chrome 13 and IE 8 but not in Firefox 5. Basically, you need to interact with the map first by zooming or panning before the onclick returns something. I had this problem in Flex and got around it by adding in an alert box in the initialization. Closing the alert box provided the map interaction necessary to allow the map click to work without panning or zooming. ... View more

Hi Carlos, I'm glad to hear you're making progress. Since you don't have the code to show why the Clip process didn't run, examine the Results information in ArcMap to find out what happened. Could it be that it's not overwriting "in_memory\APP_ENS_OVERLAP"? Have you set the Geoprocessor to overwrite outputs, either through the Geoprocessing Options dialog or by setting pGeoprocessor.OverwriteOutput = "true" ... View more

My code makes calls to functions containing the geoprocessing tools.

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> ...

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.
