Flex 3 Webservice Request (setting value in the request from text field)

Question

I have basic web service and I’m having problems sending proper request. If I send only text in the elements on the request the call is successful, but if I try to get value from text field and send in the request the value isn’t sent.

I’m not sure why this is happening.

Here is the code:

    import mx.rpc.events.ResultEvent;

private function responseData(e:ResultEvent):void {
    trace(XML(e.result));
    trace(XML(e.result).*::a);
}

 <mx:WebService id="userRequest" wsdl="WSDL.wsdl">
    <mx:operation name="Login"
     fault="mx.controls.Alert.show(event.fault.faultString)"
     result="responseData(event)" resultFormat="xml">
        <mx:request format="xml" xmlns="http://www.test.com/schemas/Test/Schema.xsd"&gt;
                <root>
                    <a>{temp.text}</a>
                    <a>3</a>
                    <b>
                        <c>1</c>
                        <d>2</d>
                    </b>
                </root>
        </mx:request>
    </mx:operation>
</mx:WebService>

 <mx:TextInput x="10" y="10" id="temp"/>
 <mx:Button x="178" y="10" label="Button" click="{userRequest.Login.send();}"/>

And here is the request that is sent:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt;
<SOAP-ENV:Body>
    <root xmlns="http://www.test.com/schemas/Test/Schema.xsd"&gt;
        <a/>
        <a>3</a>
        <b>
            <c>1</c>
            <d>2</d>
        </b>
    </root>
</SOAP-ENV:Body>

Any suggestions? Thanks
