When you create a layer in ActionScript, it's id is initially null. You can set it or the API will set it to a generic value. In MXML the id is set for you by the MXML compiler. ... View more

You need to set the UniqueValueRenderer's defaultSymbol to be used by the other observations. If a renderer returns null, the graphic is not drawn. ... View more

You could set the latestObservationRenderer and observationRenderer to instances of UniqueValueRenderer, where the UniqueValueRenderer has a defaultSymbol used by most observations and then a UniqueValueInfo with the symbol to use for a particular observation. For the latestObservationRenderer, you could set the UniqueValueInfo.attribute to be the object id field name and then set the corresponding value in the UniqueValueInfo. For the observationRenderer's UniqueValueRenderer, you'd need to set the attribute to some kind of track id field that is common to all the features in a track. Once you have the renderer set up, you can make the FeatureLayer redraw by resetting it on itself.     featureLayer.renderer = featureLayer.renderer; Another option is to create a custom Renderer class that can return the symbol you want based on your own logic. ...

Just a small clarification... you don't actually need to create empty strings at unused indexes. It's OK to use a sparse array like this: <mx:Script>         <![CDATA[             private function test():void             {                 var dynLay:ArcGISDynamicMapServiceLayer = myMap.getLayer("Region") as ArcGISDynamicMapServiceLayer;                 var layerDefArr:Array = new Array();                 layerDefArr[5] = "OBJECTID=1";                 dynLay.layerDefinitions = layerDefArr;             }         ]]>     </mx:Script> ...

Now that Navigation has been sparkified, it'd be best to just use a custom skin to add your buttons. The source files for the skins are in the skins folder in the API zip file. Here's an example where I copied the NavigationSkin to a skins folder in my project and modified it. <?xml version="1.0" encoding="utf-8"?> <!-- Copyright (c) 2010 ESRI All rights reserved under the copyright laws of the United States and applicable international laws, treaties, and conventions.

Thanks for this test case. This does appear to be a bug in the Map. The zoom control is actually setting the map's level. Did my earlier solution work? Here's a workaround if you still want to use scale. <?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.layers.supportClasses.LOD;                         protected function setMapScale(value:Number):void             {                 for each (var lod:LOD in map.lods)                 {                     if (lod.scale == value)                     {                         map.level = lod.level;                         break;                     }                 }             }         ]]>     </mx:Script>     <mx:Number id="testScale">2000000</mx:Number>         <mx:HBox>         <mx:Button label="Set Map Scale to: {testScale}" click="setMapScale(testScale)"/>         <mx:Label text="Map Scale: {map.scale}"/>     </mx:HBox>         <esri:Map id="map" extentChange="trace(event)">         <esri:ArcGISTiledMapServiceLayer             url="http://213.225.144.91/arcgis_gps_staging/rest/services/PlacesIMFMapping/MapServer"/>     </esri:Map>     </mx:Application> ...
