I have gotten the geometry service to select a buffer on my map. Although, within the buffer I can???t identify anything. I am using the IdentifyTask object to perform this operation. Within the IdentifyTask I am passing the IdentifyParameters object to the IdentifyTask.execute and using the AsyncResponder to handle the results of the execute. Nothing is happening when I hit the IdentifyTask.execute it is not completing or faulting. It is not identifying any features on the map. Do you have any ideas on why the execute is not working? Any help would be much appreciated.here is a snippet of the code that I am using. I have verified that all the map service and layer index from the XML file is correct. private function activateIdentifyTool(type:String):void { var status:String = "Buffer"; if(type == 'point') { setMapAction(DrawTool.MAPPOINT, status, sms, drawEnd); } } private var bufferGraphic:Graphic; private function drawEnd(event:DrawEvent):void { clear(); var i:int = 0; var hg:HGroup; var ch:spark.components.CheckBox; var id:Number; selectedLyrArray = []; for(i =0; i < vb1.numChildren;i++) { hg = vb1.getElementAt(i) as HGroup; ch = hg.getElementAt(0) as spark.components.CheckBox; if (ch.selected == true) { id = Number(ch.id); selectedLyrArray.push(id); } } for(i =0; i < vb2.numChildren;i++) { hg = vb1.getElementAt(i) as HGroup; ch = hg.getElementAt(0) as spark.components.CheckBox; if (ch.selected == true) { id = Number(ch.id); selectedLyrArray.push(id); } } if (selectedLyrArray.length == 0) { Alert.show("No Layers Are Selected"); } else { var geom:Geometry = event.graphic.geometry; var g:Graphic = new Graphic(geom, sms); graphicsLayer.add(g); var bp:BufferParameters = new BufferParameters(); bp.geometries = [g.geometry]; bp.distances = [ns.value]; if (cboUnits.selectedIndex == 1) { bp.unit = GeometryService.UNIT_FOOT; } else { bp.unit = GeometryService.UNIT_STATUTE_MILE; } //bp.bufferSpatialReference = new SpatialReference(102100); geometryService.addEventListener(GeometryServiceEvent.BUFFER_COMPLETE, onBufferComplete); geometryService.buffer(bp); function onBufferComplete(event:GeometryServiceEvent):void { bufferGraphicsLayer.clear(); bufferGraphic = new Graphic; //In this version of esri the geometryService returns geometries instead of graphics. bufferGraphic.geometry = event.result[0] as Polygon; var sls:SimpleLineSymbol = new SimpleLineSymbol("dash",0xff0000,.8,2); var sfs:SimpleFillSymbol = new SimpleFillSymbol("solid",0xff0000,.2,sls); bufferGraphic.symbol = sfs; var attribs:Object = { distance: ns.value, unit: bp.unit } bufferGraphic.attributes = attribs; bufferGraphicsLayer.add(bufferGraphic); startIdentify(); } } } private function startIdentify():void { showMessage("Processing Results...",true); showStateResults(); selectionGraphicsAC = new ArrayCollection(); identifyArrayCollection = new ArrayCollection(); identifycounter = 0; identifyTask = new IdentifyTask(lyrList[selectedLyrArray[identifycounter]].@mapservice); identifyParams = new IdentifyParameters(); identifyParams.returnGeometry = true; identifyParams.tolerance = 1; identifyParams.width = map.width; identifyParams.height = map.height; identifyParams.mapExtent = map.extent; identifyParams.geometry = bufferGraphic.geometry; identifyParams.layerIds = [lyrList[selectedLyrArray[identifycounter]].@layerIndex]; identifyParams.layerOption = IdentifyParameters.LAYER_OPTION_ALL; identifyParams.spatialReference = map.spatialReference; identifyTask.execute(identifyParams, new AsyncResponder(identifyCompleteHandler,myFaultFunction)); } private function myFaultFunction(error:Object):void { Alert.show(String(error), "Identify Error"); } private function identifyCompleteHandler(results:Array):void { Alert.show("I am here in identifyCompleteHandler"); identifycounter++; processIdentifyResults(results, identifycounter-1); }
