EncodingError when Webservice and SoapHeader

Question

Hi All,
does anybody know a solution for this:
Call a webservice works fine without identification. But to
send Credentials I add a SoapHeader. Then I get an error #1009 The
access to properties or methods of a null-objectreference is not
allowed.
And when I debug this it all stops in a operation.as at line
764. Here are the lines
764 soap = encoder.encodeRequest(pc.args, pc.headers);
catch(fault:Fault)
dispatchRpcEvent(FaultEvent.createEvent(fault));
return;
catch(error:Error)
var errorMsg:String = error.message ? error.message : "";
var fault2:Fault = new Fault("EncodingError", errorMsg);
var faultEvent:FaultEvent = FaultEvent.createEvent(fault2);
dispatchRpcEvent(faultEvent);
return;
And here is the code where I call the webservice:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="vertical" height="186" width="316">
<mx:WebService
id="userRequest"
wsdl="
http://mitbb01.make-it.local/mywebservice.nsf/wsecho?WSDL"
load="headers();">
<mx:operation name="ECHO" resultFormat="object"
fault="mx.controls.Alert.show(event.fault.faultString)"
result="showResult(event)" />
</mx:WebService>
<mx:Script>

import mx.rpc.events.ResultEvent;
import mx.rpc.events.FaultEvent;
import mx.rpc.soap.*;
import mx.rpc.soap.SOAPHeader;
private var header1:SOAPHeader;
public function headers():void {
// Create QName and SOAPHeader objects.
var q1:QName=new QName("
http://soapinterop.org/xsd",
"Header1");
header1=new SOAPHeader(q1, {userName:"admin
makeit",Password:"kennwort"});
// Add the header1 SOAP Header to all web service requests.
userRequest.addHeader(header1);
private function showResult(e:ResultEvent):void
ti_Response.text = userRequest.ECHO.lastResult;
private function send_data(linie:String):void
userRequest.ECHO(linie);
]]>
</mx:Script>
<mx:TextInput id="ti_Request" text="lalala"/>
<mx:Button label="Send"
click="send_data(ti_Request.text)" />
<mx:TextInput id="ti_Response"/>
</mx:WindowedApplication>
What goes wrong. Is there a workaround. Please help. Thanx
for any help in advance.
Regards
Andreas

Sorry for my late response, but I did not look at this after it was solved and I did not receive any mail. So please let me know if you still need some support.
I could send you a document with some screen shots. If so send me an email ([email protected])
