title: Unmarshalling Error
body: <p>I get an error whenever I try do a request to a SOAP service:</p>
  
  <blockquote>
    <p>Unmarshalling Error: unexpected element (uri:"http://www.domain.com/ws/servicename/", local:"dummyArg"). Expected elements are &lt;{}dummyArg></p>
  </blockquote>
  
  <p>The method that I'm calling has is defined as:</p>
  
  <pre><code>function GetTxServer(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): TxServer;
  </code></pre>
  
  <p>I have little experience with SOAP, and I couldn't find any useful information on this. Feel free to ask any question that might speed up the process in finding the issue.</p>
  
  <p>I believe that the way that I am calling the function is not the correct way!</p>
  
  <p>I'm using Delphi 2010, and I've called the method like so:</p>
  
  <pre><code>Response := GetTxServer.requestIVULoto(cm);
  </code></pre>
