Reprojecting Address Locator in Flex API

JenniferGrew1 — Mon, 25 Jul 2011 16:02:50 GMT

I am new to ArcGIS API for Flex and want to use the address locator in a map using locally projected data layers. Everything is local and rscheitlin posts for this very issue in the Flex Viewer http://forums.arcgis.com/threads/2666-Locator-in-sample-working-but-still-using-wrong-coordinate-system?highlight=Flex+Arcgis+locator were very useful, but i can't seem to translate it over to the API. I apologize for the layout of the code below, it is scattered in several places throughout the mxml.

Here is what we have so far:

// Look up for Address
 private function doFind():void
 {
 var myAddress:Object =
 {
 Address: address.text,
 City: city.text,
 State: state.text,
 Zip: zip.text,
 /* Country: country.selectedItem */
 Country: "USA"
 };
 // Use outFields to get back extra information
 // The exact fields available depends on the specific Locator used.
 var myOutFields:Array = [ "Loc_name" ];
 locateTask.addressToLocations(myAddress, myOutFields, new AsyncResponder(onResult, onFault));
 function onResult(candidates:Array, token:Object = null):void
 {
 if (candidates.length > 0)
 {

 var addressCandidate:AddressCandidate = candidates[0];
 var myGraphic:Graphic = new Graphic();
 //trace(addressCandidate.location);
 myGraphic.geometry = WebMercatorUtil.geographicToWebMercator(addressCandidate.location);

 //trace(myGraphic.geometry);
 myGraphic.symbol = mySymbol;
 myGraphic.toolTip = addressCandidate.address.toString();
 myGraphic.id = "graphic";
 geocodeLayer.add(myGraphic);
 mainMap.centerAt(myGraphic.geometry as MapPoint);


 // Zoom to an appropriate level
 // Note: your tile levels and LOC_NAME might differ...
 if (addressCandidate.attributes.Loc_name.search("RoofTop") > 0)
 {
 mainMap.scale = 10000;
 }
 else if (addressCandidate.attributes.Loc_name.search("Address") > 0)
 {
 mainMap.scale = 10000;
 }
 else if (addressCandidate.attributes.Loc_name.search("Street") > 0)
 {
 mainMap.scale = 15000;
 }
 else if (addressCandidate.attributes.Loc_name.search("Zipcode") > 0)
 {
 mainMap.scale = 40000;
 }
 else if (addressCandidate.attributes.Loc_name.search("City") > 0)
 {
 mainMap.scale = 150000;
 }
 else
 {
 mainMap.scale = 500000;
 }
 //myInfo.htmlText = "Found: " + addressCandidate.address.toString(); // formated address
 }
 else
 {
 //myInfo.htmlText = "Found nothing :(";
 Alert.show("Sorry, couldn't find a location for this address"
 + "\nAddress: " + address.text
 + "\nCity: " + city.text
 + "\nZIP Code: " + zip.text
 + "\nState: " + state.text
 /* + "\nCountry: " + country.selectedItem) */
 + "\nCountry: USA");
 }
 }

Jennifer,

You need to set the outSpatialReference of the locator task.

<esri:Locator id="locateTask"  url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Locators/ESRI_Geocode_USA/GeocodeServer" outSpatialReference="{mainMap.spatialReference}"/>

and then change this line:

myGraphic.geometry =addressCandidate.location;
