    copied!<p>I'm new to flex and I am building a wrapper class for the WebService object to make my main code mxml cleaner. I am trying to pass a function to a class method to set as the result event handler for the soap call and it is not working as expected.</p> <p>Here is the class:</p> <pre><code>package { import mx.rpc.events.ResultEvent; import mx.rpc.soap.WebService; public class WebServiceObject { private var wsdl:String = "http://localhost:8080/WebApplication1/TestWs?wsdl"; private var testWs:WebService; public function WebServiceObject() { try { testWs = new WebService(wsdl); testWs.loadWSDL(); } catch(errObject:Error) { trace(errObject.toString()); } } public function getSomething(resultHandler:Function):void { testWs.getSomething.addEventListener(ResultEvent.RESULT, resultHandler); testWs.getSomething.send(); } } } </code></pre> <p>This is the mxml:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"&gt; &lt;mx:Script&gt; &lt;![CDATA[ import WebServiceObject; import mx.rpc.events.ResultEvent; import mx.controls.Alert; private function test():void { var test:WebServiceObject = new WebServiceObject(); test.getSomething(handler); } public function handler(event:ResultEvent):void { trace(event.result); } ]]&gt; &lt;/mx:Script&gt; &lt;mx:Button label="Test" click="test();"/&gt; &lt;/mx:Application&gt; </code></pre> <p>The web service call is started and the call goes out but the result does not get passed back to the event listener. I tried using a class method as the handler and got the same result. All the pieces work if they are in the mxml code tag.</p> <p>Is this doable? Am I missing something?</p> <p>Thanks.</p> <p>EDIT:</p> <p>OK apparently (this didn't work):</p> <pre><code>testWs = new WebService(wsdl); testWs.loadWSDL(); </code></pre> <p>is not the same as (this did work, note where the wsdl URL is passed in):</p> <pre><code>testWs = new WebService(); testWs.loadWSDL(wsdl); </code></pre> <p>and I was quite sure that I tried it both ways... anyway problem solved.</p>
