Hello, I am using 'Geode an address' sample from resources website with my own geocode server services for a test but I got some ActionScript error messages after click on"Find Adress" button. On my own services, I only have 'Street' for address Fields. Can someone let me know why I got these messages? ********************* Here are ActionScript error: ********************* TypeError: Error #1010: A term is undefined and has no properties. at testing/private:doFind/onResult() at mx.rpc::AsyncResponder/result() at com.esri.ags.tasks::Locator/handleAddressCandidates() at Function/http://adobe.com/AS3/2006/builtin::call() at com.esri.ags.tasks::BaseTask/handleResult() at <anonymous>() at mx.rpc::Responder/result() at mx.rpc::AsyncToken/http://www.adobe.com/2006/flex/mx/internal::applyResult() at mx.rpc.events::ResultEvent/http://www.adobe.com/2006/flex/mx/internal::callTokenResponders() at HTTPOperation/http://www.adobe.com/2006/flex/mx/internal::dispatchRpcEvent() at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::resultHandler() at mx.rpc::Responder/result() at mx.rpc::AsyncRequest/acknowledge() at DirectHTTPMessageResponder/completeHandler() at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at flash.net::URLLoader/onComplete()

Solution: Use the addressToLocations() method on the Locator.
This sample takes a user-provided address and sends it to the server for geocoding. When the response comes back, the OnResult() function creates a graphic for the result and then sets the scale appropriately based on if the match was a "street", "city" etc match. --> <mx:Script> <![CDATA[ import com.esri.ags.Graphic; import com.esri.ags.tasks.AddressCandidate; import mx.controls.Alert; import mx.rpc.AsyncResponder;
