Hello,I have published a network analyst service and I'm trying to use it from the Flex API 3.1.When I use the service in ArcMap or through the rest GUI in a browser, the service returns the right answer.When I use the service from the Flex API 3.1, my object "routeResult" that contain the route returned by the server is null. I get the error: "Error #1009: Cannot access a property or method of a null object reference." for the object routeResult.Here my application code:<?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" xmlns:layers="com.esri.ags.layers.*" minWidth="1000" minHeight="600" viewSourceURL="Source/index.html"> <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[ import com.esri.ags.events.MapMouseEvent; import com.esri.ags.events.RouteEvent; import com.esri.ags.FeatureSet; import com.esri.ags.Graphic; import com.esri.ags.symbols.CompositeSymbol; import com.esri.ags.symbols.SimpleMarkerSymbol; import com.esri.ags.symbols.TextSymbol; import com.esri.ags.tasks.supportClasses.RouteResult; import mx.controls.Alert; import mx.rpc.events.FaultEvent; [Bindable]private var stops:FeatureSet = new FeatureSet([]); [Bindable]private var lastRoute:Graphic; private function mapClickHandler(event:MapMouseEvent):void { var stopSymbol:CompositeSymbol = new CompositeSymbol(); var circleSym:SimpleMarkerSymbol = new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE, 20, 0x000099); var textSym:TextSymbol = new TextSymbol(String(stops.features.length + 1)); textSym.textFormat = new TextFormat("Verdana", null, null, true); textSym.color = 0xFFFFFF; stopSymbol.symbols = [ circleSym, textSym ]; var stop:Graphic = new Graphic(event.mapPoint, stopSymbol); inputsLayer.add(stop); stops.features.push(stop); if (stops.features.length > 1) { routeTask.solve(routeParams); } } private function solveCompleteHandler(event:RouteEvent):void { var routeResult:RouteResult = event.routeSolveResult.routeResults[0]; lastRoute = routeResult.route; lastRoute.toolTip = routeResult.routeName; if (routeResult.route.attributes.Total_Time) { lastRoute.toolTip += " in " + Math.round(Number(routeResult.route.attributes.Total_Time)) + " minutes."; } } private function faultHandler(event:FaultEvent):void { Alert.show(event.fault.faultString + "\n\n" + event.fault.faultDetail, "Routing Error " + event.fault.faultCode); // Supprimer le dernier stop ou les deux s'il n'y en a pas plus. if (stops.features.length <= 2) { inputsLayer.clear(); stops = new FeatureSet([]); } else { inputsLayer.remove(stops.features.pop()); } } ]]> </fx:Script> <fx:Declarations> <esri:MapPoint id="mapPoint" x="655672" y="6861079"/> <esri:RouteTask id="routeTask" concurrency="last" fault="faultHandler(event)" requestTimeout="30" showBusyCursor="true" solveComplete="solveCompleteHandler(event)" url="http://serverIP:8399/arcgis/rest/services/na_service/MapServer/Route"/> <esri:RouteParameters id="routeParams" stops="{stops}" returnDirections="false"/> <esri:SimpleLineSymbol id="routeSymbol" width="5" alpha="0.6" color="0x000099"/> </fx:Declarations> <s:BorderContainer id="applicationHolder" width="100%" height="100%"> <s:layout> <s:VerticalLayout/> </s:layout> <s:SkinnableContainer id="headerBar" width="100%" height="50" backgroundColor="0xcccccc"> <s:layout> <s:HorizontalLayout verticalAlign="middle"/> </s:layout> <mx:Text id="titleText" fontSize="25" fontWeight="bold" text="My application"/> <mx:Spacer width="75"/> </s:SkinnableContainer> <esri:Map id="mainMap" width="100%" height="100%" center="{mapPoint}" crosshairVisible="{crosshairsCheck.selected}" level="16" mapClick="mapClickHandler(event)" panArrowsVisible="{panArrowsCheck.selected}"> <esri:ArcGISDynamicMapServiceLayer url="http://serverIP:8399/arcgis/rest/services/myMapService/MapServer"/> <esri:GraphicsLayer graphicProvider="{lastRoute}" symbol="{routeSymbol}"/> <esri:GraphicsLayer id="inputsLayer"/> </esri:Map> </s:BorderContainer> </s:Application>Do you have any advice?Regards
