An ArcGIS Server 10 layer can include a Renderer in the Drawing Info. e.g. http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Earthquakes/EarthquakesFromLastSevenDays/MapServer/0 The Flex API's FeatureLayer will use this by default. If you're using a layer that does not have any Drawing Info, then the default symbology is used. You can set a renderer or symbol on the FeatureLayer since these properties are inherited from GraphicsLayer: http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/GraphicsLayer.html ...

Since it's a bindable property you can use the ChangeWatcher.watch() method.

When I try your code, there are many features being returned from both layers, but the code is only using the first one. Line 76: var result:IdentifyResult = results[0]; If you add a breakpoint on this line and run the debugger, it should stop here and then you can inspect the results Array to see all the results. Another way to debug this is to use a tool like HttpFox to see the request and response and you can open the urls in a new tab and change f=json to f=html to see the results in the Service Directory. You may want to consider having a DataGrid for each layer where you can view the attributes for all the features that are returned. I'd also recommend setting identifyParams.returnGeometry to false if you're not going to add the features being returned to the map. This will improve the performance. ... View more

To get the features from a FeatureLayer, you can use the inherited graphicProvider property: http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/GraphicsLayer.html#graphicProvider FeatureSet.attributes is really nothing more than the extractAttributesFromFeatures function Rene has posted. You could get the attributes like this: var attributes:Array = new FeatureSet(ArrayCollection(featureLayer.graphicProvider).toArray()).attributes; Reference: http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/FeatureSet.html#attributes ...

I'd try the IdentifyTask where the IdentifyParameters.layerOption is set to IdentifyParameters.LAYER_OPTION_ALL and set the IdentifyParameters.layerIds to the id's of the two layers you want to get the attributes for.

Hi Joey, I took a look at this with a REST expert and was told that you'll need to publish a raster catalog as part of a geodatabase and to make sure that you have a Date field selected for the start time field. Currently your layers have no fields. You may want to contact http://support.esri.com for more help with getting this set up. ... View more

Here's an example. I've modified IdentifySample.mxml to use a 10.0 service. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:esri="http://www.esri.com/2008/ags">     <mx:Script>         <![CDATA[             import com.esri.ags.Graphic;             import com.esri.ags.events.MapMouseEvent;             import com.esri.ags.symbol.InfoSymbol;             import com.esri.ags.tasks.IdentifyParameters;             import com.esri.ags.tasks.IdentifyResult;             import mx.controls.Alert;             import mx.rpc.AsyncResponder;                         private function mapClickHandler(event:MapMouseEvent):void             {                 clickGraphicsLayer.clear();                 var identifyParams:IdentifyParameters = new IdentifyParameters();                 identifyParams.returnGeometry = true;                 identifyParams.tolerance = 3;                 identifyParams.width = myMap.width;                 identifyParams.height = myMap.height;                 identifyParams.geometry = event.mapPoint;                 identifyParams.mapExtent = myMap.extent;                 identifyParams.spatialReference = myMap.spatialReference;                                var clickGraphic:Graphic = new Graphic(event.mapPoint, clickPtSym);                 identifyTask.execute(identifyParams, new AsyncResponder(myResultFunction, myFaultFunction, clickGraphic));                 clickGraphicsLayer.add(clickGraphic);             }             private function myResultFunction(results:Array, clickGraphic:Graphic = null):void             {                 if (results && results.length > 0)                 {                     var result:IdentifyResult = results[0];                     var resultGraphic:Graphic = result.feature;                                         // update clickGraphic (from mouse click to returned feature)                     clickGraphic.symbol = new InfoSymbol(); // use default renderer                     clickGraphic.attributes = resultGraphic.attributes;                 }             }                         private function myFaultFunction(error:Object, clickGraphic:Graphic = null):void             {                 Alert.show(String(error), "Identify Error");             }         ]]>     </mx:Script>         <!-- start declarations -->         <!-- Symbol for where the user clicked -->         <esri:SimpleMarkerSymbol id="clickPtSym" style="x" color="0xFF0000" size="12"/>                 <!-- Identify Task -->         <esri:IdentifyTask id="identifyTask"             concurrency="last"             url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Earthquakes/EarthquakesFromLastSevenDays/MapServer?layerDefs=0:magnitude &gt; 5"/>     <!-- end declarations -->     <esri:Map id="myMap" mapClick="mapClickHandler(event)" openHandCursorVisible="false">         <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Shaded_Relief/MapServer"/>         <esri:ArcGISDynamicMapServiceLayer url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Earthquakes/EarthquakesFromLastSevenDays/MapServer">             <esri:layerDefinitions>                 <mx:String>magnitude &gt; 5</mx:String>             </esri:layerDefinitions>         </esri:ArcGISDynamicMapServiceLayer>         <esri:GraphicsLayer id="clickGraphicsLayer"/>     </esri:Map> </mx:Application> ...

Hi Robert, Here's a sample that gives me two events.

If you're using PictureMarkerSymbols, then the Graphic has a child and you get mouseOver events for it as well that bubble up to the Graphic. A simple alternative is to use the rollOver/Out events instead. Another option is to check the event's target.

Version 2 of the API still supports ArcGIS Server 9.3. Also, in version 2, you can now place the ScaleBar like any other component outside of the Map. e.g. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"                xmlns:s="library://ns.adobe.com/flex/spark"                xmlns:mx="library://ns.adobe.com/flex/mx"                xmlns:esri="http://www.esri.com/2008/ags">     <s:layout>         <s:VerticalLayout horizontalAlign="center"/>     </s:layout>     <esri:Map id="map" scaleBarVisible="false">         <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>     </esri:Map>     <esri:ScaleBar map="{map}"/>     </s:Application> ...
