Hello there, I am using flex viewer 3.1, and was trying out "query for statistics" example at :http://resources.arcgis.com/en/help/flex-api/samples/index.html#//01nq00000070000000 I modified the code a bit so that the data can be viewed in the datagrid(and I don't need to do fancy stats stuff), but I am getting "Invalid or missing input parameters error".Here is my full mxml file content<?xml version="1.0" encoding="utf-8"?> <viewer:BaseWidget 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:viewer="com.esri.viewer.*" xmlns:esri="http://www.esri.com/2008/ags" widgetConfigLoaded="init()"> <fx:Script> <![CDATA[ import com.esri.ags.events.QueryEvent; import com.esri.ags.tasks.supportClasses.Query; import com.esri.ags.tasks.supportClasses.StatisticDefinition; import mx.collections.ArrayCollection; import mx.controls.Alert; import mx.events.FlexEvent; import mx.rpc.events.FaultEvent; //this function called when the widget's configuration is loaded private function init():void { var query:Query = new Query(); //query.where = "STATE_NAME = 'Alaska' AND TYPE = 'city'"; query.returnGeometry = false; query.outFields = ["STATE_NAME"]; queryTask.execute(query); } protected function queryTask_executeCompleteHandler(event:QueryEvent):void { var fields:Array = event.featureSet.fields; var attributes:Array = event.featureSet.attributes; dg.dataProvider = new ArrayCollection(attributes); } protected function esri_faultHandler(event:FaultEvent):void { Alert.show("Error: " + event.fault.faultString, "Error code: " + event.fault.faultCode); } protected function sumLabelFunction(item:Object, column:GridColumn):String { return numberFormatter.format(item["POP_SUM"]); } ]]> </fx:Script> <fx:Declarations> <!-- Query Task --> <esri:QueryTask id="queryTask" executeComplete="queryTask_executeCompleteHandler(event)" fault="esri_faultHandler(event)" url="http://it.innovateteam.com/arcgis/rest/services/OTIS/TestWebServiceForQueries/MapServer/1"/> <s:NumberFormatter id="numberFormatter" trailingZeros="false"/> </fx:Declarations> <viewer:WidgetTemplate id="frTable" width="500" height="500"> <viewer:layout> <s:VerticalLayout horizontalAlign="center" verticalAlign="middle"/> </viewer:layout> <s:DataGrid id="dg" width="280" right="20" top="20"> <s:columns> <s:ArrayList> <s:GridColumn dataField="STATE_NAME" headerText="US State"/> </s:ArrayList> </s:columns> </s:DataGrid> </viewer:WidgetTemplate> </viewer:BaseWidget>
When I manually query http://it.innovateteam.com/arcgis/rest/services/OTIS/TestWebServiceForQueries/MapServer/1, I can see the STATE_NAME attribute and values. Please help me out on figuring out what I am doing wrong. Thanks.
