I remember seeing a post where a user ran into the maximum number of layers (around 20 or so) that could be added to a map, but I haven't been able to find the thread. ... View more

You can use the Map's Reorder method to change the order of the layers. ... View more

I didn't wrap my legend in a scroller, but put it in a VGroup along with a transparency slider.     <s:VGroup id="legendGroup" width="100%" height="100%" visible="{layerBenthic.visible}">         <s:HGroup width="100%" horizontalAlign="center" paddingTop="10">             <s:VGroup width="100%" horizontalAlign="center">                 <s:Label text="Layer Transparency"/>                 <s:HSlider id="toolAlpha" minimum="0" maximum="100" snapInterval="1" liveDragging="true"                            width="75%" change="changeTransparency()" value="100"/>             </s:VGroup>         </s:HGroup>         <esri:Legend id="legendMap" map="{mapMain}" layers="{layerBenthic}" width="100%" height="100%"                      respectCurrentMapScale="true" x="10" />     </s:VGroup> ...

Hi Robert, I've been using your Navigation tool in one of my projects, where the code has been put into a separate directory and linked to the project by Source Path. It's a great tool that I really appreciate your work on and it's been working just as expected. However, I've started another project (FB 4.5.1 and API 2.4) and have set it up the same way, but here I'm getting the error The skin part type 'mx.controls:VSlider' must be assignable to 'spark.components.supportClasses:SliderBase'. in the line [HostComponent("com.esri.ags.components.Navigation")] Why would this work in one project but not the other? ...

You will not find the references for the Geoprocessing tools using "Add ArcGIS Reference". You'll have to use "Add Reference" and select the .NET tab. ... View more

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> ...
