Generated requests & responses miss namespace prefix

Hello,

I've got a very basic WSDL, and I've let SoapUI generate a sample request and a mock service for it. Inner elements of the generated request & response lack, however, the namespace prefix:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:exam="http://www.example.com/">
   <soapenv:Header/>
   <soapenv:Body>
      <exam:getGreeting>
         <!--Optional:-->
         <name>?</name>
      </exam:getGreeting>
   </soapenv:Body>
</soapenv:Envelope>

The <name> element herein should not be in the anonymous namespace, it should have the "exam" prefix, as like as the <getGreeting> element does. The same problem is in the response that I get from the mock service.

The XSD looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema version="1.0" targetNamespace="http://www.example.com/" xmlns:tns="http://www.example.com/" xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="getGreeting" type="tns:TgetGreeting"/>

  <xs:element name="getGreetingResponse" type="tns:TgetGreetingResponse"/>

  <xs:complexType name="TgetGreeting">
    <xs:sequence>
      <xs:element name="name" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="TgetGreetingResponse">
    <xs:sequence>
      <xs:element name="return" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

and the WSDL is as follows:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- Generated by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is Oracle JAX-WS 2.1.5. -->

      <soap:address location="http://localhost:7001/business/hello/HelloWorldService"/>
    </port>
  </service>
</definitions>

I use SoapUI 4.0.1, Build dist-134-2011-09-14, Build Date 2011/09/14 13:06.
