There's not an easy way to get to the Graphic from the InfoWindow. It sounds like you're using Graphic.infoWindowRenderer. If you also listen for click on the Graphic, you can save the clicked Graphic to a var and then refer back to it in the zoomHandler. The zoomHandler should take an Event, since that's what is being dispatched. You should be getting an error otherwise when you debug the app or use the Flash Debug player. ... View more

The map's spatialReference property is read-only since we don't officially support changing it. Technically, it can be changed though by setting map.spatialReference.wkid. You'll also need to reproject any client side graphics. ... View more

If the spatial reference of your map is web mercator, then it will convert to geographic. Try running config-all.xml for an example. If the spatial reference of your map is geographic, then no conversion is required, but if it's something else, you won't see geographic values. ... View more

There's not an easy way to handle this now. I'll enter an enhancement request to have FeatureLayerEvent.features populated for a "selectionClear" event. In the meantime, try doing this when you get a "selectionComplete" event: var featureLayer:FeatureLayer = event.featureLayer; var selectedFeatures:Array = featureLayer.selectedFeatures; for each (var graphic:Graphic in featureLayer.graphicProvider) {     if (graphic.toolTip && selectedFeatures.indexOf(graphic) == -1)     {         graphic.toolTip = null;     } } ...

The Geometry Service's "Areas and Lengths" operation measures the area in the spatial reference of the input geometry, which in this case is web mercator. The web mercator projection stretches areas the further you go from the equator. I've updated the sample below to first project the polygon to 54034 (World_Cylindrical_Equal_Area). This will give more accurate results, but it's best to use an appropriate projection for the area you're measuring. For even better results, you can use the Geometry Service to densify the polygon before projecting it. <?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"                pageTitle="Measure Areas">     <!--          This sample shows how to use the DrawTool and GeometryService to:          - simplify ("clean") the drawn polygon          - measure the area of the polygon          - create a properly placed label for the polygon          Workflow for this sample:          1.
