title: Unable to call request in SoapUI - Ambiguous method overloading
body: <p>I use following code in <code>SoapUI</code> SOAP request as a <code>Script Assertion</code> to get value from xml output:</p>
  
  <pre><code>import java.text.SimpleDateFormat
  import com.eviware.soapui.support.XmlHolder
  
  def xml = new com.eviware.soapui.support.XmlHolder(context.response)
  def fname = xml.getNodeValue("//*:name")
  </code></pre>
  
  <p>It is working well, when I execute request directly, but get error message when call it from another test step with this code: <code>testStepgetAttachment.run(testRunner, context)</code></p>
  
  <p>Error message:</p>
  
  <blockquote>
    <p>Ambiguous method overloading for method
