Step by step. Do you have the same logic as in SearchWidget/BookmarkWidget/... ? [ATTACH=CONFIG]14006[/ATTACH] where each SearchResult is: var searchResult:SearchResult = new SearchResult(); searchResult.title = title; searchResult.content = content; searchResult.point = getGeomCenter(graphic); searchResult.link = link ? link : null; searchResult.linkAlias = linkAlias; searchResult.geometry = graphic.geometry; searchResult.graphic = graphic; Right? ...

This way we work with selection symbol: ... private var selectionSMS:SimpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE, 30, 0x00FF00, 0.5); // private var selectionSMS:SimpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE, 6, 0x000000, 0); ... /** * Listen feature layer update end handler */ protected function onFeatureLayerUpdated(event:LayerEvent):void {     if (featureLayer.selectedFeatures != null && featureLayer.selectedFeatures.length > 0)     {         Graphic(featureLayer.selectedFeatures[0]).symbol = selectionSMS; // for points     } } ...

Andrew, I do not understand what you want to hear, listening myfLayer.addEventListener(GraphicEvent.GRAPHIC_ADD,fLayer_graphicAddHandler);? How are going to add "Graphic"? As I understand, for FeatureLayer add() is not supported. What is your task? Why fLayer_graphicAddHandler needed? <?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"                     backgroundColor="0x9c9c9c"> <!-- Adobe Flex SDK 4.6.0 --> <!-- ArcGIS API for Flex 3.0 prerelease 15.03.2012 --> <!-- web.zone.ee/bespiva/layerwithoutmap --> <s:layout>   <s:VerticalLayout gap="10"      paddingLeft="10"      paddingRight="10"      paddingTop="10"      paddingBottom="10" /> </s:layout> <s:Label text="Load layer:" /> <s:HGroup width="100%">     <s:TextInput id="txtUrl"       width="100%"       text="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/MapServer/0" />     <s:Button label="Load"          click="onLoadButtonClick(event)" />   </s:HGroup> <s:Label text="Query results table:" /> <s:VGroup width="100%"          height="50%">     <s:DataGrid width="100%"      height="100%"      dataProvider="{gridProvider}" />   </s:VGroup> <s:Label text="Logs:" /> <s:VGroup width="100%"      height="100%">     <s:TextArea width="100%"      height="100%"      id="log" />   </s:VGroup> <fx:Script>   <![CDATA[    import com.esri.ags.FeatureSet;    import com.esri.ags.Graphic;    import com.esri.ags.events.LayerEvent;    import com.esri.ags.layers.FeatureLayer;    import com.esri.ags.tasks.supportClasses.Query;       import mx.collections.ArrayCollection;    import mx.rpc.AsyncResponder;    import mx.rpc.Fault;    import mx.utils.StringUtil;       [Bindable]    private var gridProvider:ArrayCollection = new ArrayCollection();       private var activeLayer:FeatureLayer = null;       private function addLog(message:String):void    {     log.text = StringUtil.substitute("{0}\n\n{1}", message, log.text);    }       protected function onLoadButtonClick(event:MouseEvent):void    {     addLog("onLoadButtonClick()");         if (txtUrl.text.length > 0)     {      initLayer(txtUrl.text);     }     else     {      addLog("Layer url is empty.

Andrew, but I want to do this without adding another layer to the map. var layer:Layer = map.getLayer("Metadata"); var myfLayer:FeatureLayer = new FeatureLayer(layer.url + "/0"); myfLayer.id = "MetadataFeatureLayer"; myfLayer.addEventListener(GraphicEvent.GRAPHIC_ADD,fLayer_graphicAddHandler); // add layer/table load event listener myfLayer.addEventListener(LayerEvent.LOAD, onLayerLoad, false, 0, true); dispatchEvent(new LayerEvent(LayerEvent.LOAD, myfLayer)); // the code you looked for // map.addLayer(myfLayer); ... /* * Listen layer load handler */ protected function onLayerLoad(event:LayerEvent):void {     // now you can work with loaded layer/table } Good luck. ...

Chamara, Form adobe: Cross-domain policy file specification A cross-domain policy file is an XML document that grants a web client�??such as Adobe Flash Player, Adobe Reader, etc.�??permission to handle data across multiple domains. ...

From ArcGIS FLEX Viewer help: Getting Started If this service is not running in the same web server, your ArcGIS Server will need a crossdomain.xml file. ...

Do not gone through, but read carefully. Conceptually, a widget is a chunk of code that provides functionality in the ArcGIS Viewer for Flex application. The Viewer application has an extensible widget programming model and supports modular functionality. For example, one widget enables Viewer application end-users to switch between base maps in the map display; a different widget provides functionality to find a location in the map; while another widget provides an overview map for the Viewer. You never do it for own application. "Never" means that if you do not have the experience and you do not understand "How it is made" - you can not do that. "Never" means that if you understand "How it is made" - you do not want to do it. (it is hard work - to dig into someone else's code) ... View more

1 - If you download widgets from Code Gallery. For example: Roberts search widget has README file: https://github.com/rscheitlin/eSearch/blob/master/README with detailed description "How to install compiled version" and "How to install non compiled version"... 2 - If you play with samples in Viewer ESRI developers provide us with help pages: http://help.arcgis.com/en/webapps/flexviewer/help/index.html#/Creating_widgets/01m300000010000000/ the most common mistake here: 4 - Compile your widget, like any other Flex module. In Flash Builder, with the Flex Viewer project open, go to Project > Properties > Flex modules. Click Add, click Browse, then navigate to your new widget .mxml file. Click OK three times.

Tom, yes "units" property is not in reference (I do not know why), but it is String type property and it exists: units property  units:String The units of the Map.
