How to handle soap responses

Question

I am following this tutorial to handle SOAP responses but it does not work http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_6.html
using code blew I am trying to parse the following soap response.
    <?xml version="1.0" encoding="utf-8"?>
    <s:Application 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:components="components.*"
                                     xmlns:hellos="services.hellos.*"
                                     height="957"  creationComplete="initApp()" >
              <fx:Style source="Styles.css"/>
              <fx:Script>
                        <![CDATA[
                                  import mx.controls.Alert;
                                  private namespace invesbot = "http://Services.com";
                                  use namespace invesbot;
                                  private namespace a = "http://schemas.xmlsoap.org/soap/envelope/";
                                  private namespace b = "http://www.w3.org/2001/XMLSchema";
                                  private namespace c = "http://www.w3.org/2001/XMLSchema-instance";
                                  use namespace a;
                                  use namespace b;
                                  use namespace c;
                                  [Bindable]
                                  var _result:*
                                  private function initApp():void
                                            myService.mycustomers();
                        ]]>
              </fx:Script>
              <fx:Declarations>
                        <mx:WebService id="myService" wsdl="http://localhost:8081/WebServiceTest/services/Hellos?wsdl"
                                                         showBusyCursor="true"
                                                         fault="Alert.show(event.fault.faultString), 'Error'">
                                  <mx:operation name="mycustomers" resultFormat="e4x">
                                            <mx:request>
                                            </mx:request>
                                  </mx:operation>
                        </mx:WebService>
              </fx:Declarations>
    <mx:HBox>
                        <mx:Text
                                  text="{myService.mycustomers.lastResult.mycustomersReturn.name}"
                                  />
              </mx:HBox>
    </s:Application>
The SOAP response is as following
    <?xml version="1.0" encoding="UTF-8"?>
    <soapenv:Envelope
      xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
      xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <soapenv:Body>
        <mycustomersResponse xmlns="http://Services.com">
          <mycustomersReturn>
            <age>28</age>
            <name>John</name>
          </mycustomersReturn>
          <mycustomersReturn>
            <age>29</age>
            <name>Alex</name>
          </mycustomersReturn>
          <mycustomersReturn>
            <age>30</age>
            <name>Jack</name>
          </mycustomersReturn>
        </mycustomersResponse>
      </soapenv:Body>
    </soapenv:Envelope>
Using the above code the output will be
    <name xmlns="http://Services.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">John</name>
    <name xmlns="http://Services.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Alex</name>
    <name xmlns="http://Services.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Jack</name>
but when I use the following code to put the result in dropdown box it gives the following error
    <s:FormItem label="Employee:">
                        <s:DropDownList id="dropDownList3"
                                                                labelField="name"
                                                                dataProvider ="{myService.mycustomers.lastResult.mycustomersReturn}"/>
              </s:FormItem>
TypeError: Error #1034: Type Coercion failed: cannot convert XMLList@106e9af1 to mx.collections.IList.

Hi Ashish,
You can use Catch All error handler within scope of InvokeService action. By specifying SOAP Fault variable name there, response soap fault will be populated in variable.
In 11g(As per observation), split joins are strict towards definition of input and output message based on WSDL of target service which causes exception for invalidMessage in InvokeService action.
Hope this helps.
