SOAP web service: null parameter if namespace not declared in envelope

Question

Hi guys,
We are exposing a SOAP web service on WebLogic Portal 10.0. The service has one method which takes a single parameter. The service works correctly if the namespace is declared in the envelope element, but it is unable to map the request correctly if the namespace is declared on each request element and so the single parameter is null.
This works:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inv="http://company.com/inventory">
   <soapenv:Header/>
   <soapenv:Body>
      <inv:CheckProductReservation>
         <username>6144</username>
         <udac>GP1</udac>
         <directoryYpgCode>00903</directoryYpgCode>
         <headingCode>0000001005</headingCode>
         <validityStartDate>2009-09-01</validityStartDate>
         <validityEndDate>2010-08-31</validityEndDate>
         <reservationCode>1234</reservationCode>
      </inv:CheckProductReservation>
   </soapenv:Body>
</soapenv:Envelope>This fails:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <SOAP-ENV:Body>
      <CheckProductReservation xmlns="http://company.com/inventory">
         <username xmlns="http://company.com/inventory">6144</username>
         <udac xmlns="http://company.com/inventory">GP1</udac>
         <directorycompanyCode xmlns="http://company.com/inventory">00903</directorycompanyCode>
         <headingCode xmlns="http://company.com/inventory">0000001005</headingCode>
         <validityStartDate xmlns="http://company.com/inventory">2009-09-01</validityStartDate>
         <validityEndDate xmlns="http://company.com/inventory">2010-08-31</validityEndDate>
         <reservationCode xmlns="http://company.com/inventory">1234</reservationCode>
      </CheckProductReservation>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>These two requests seem equivalent and syntactically correct. Interestingly enough, soapUI seems to think that the 2nd request is not valid.
Any ideas why the 2nd request is not working?
Thanks!

The WSDL doesn't define the elementNameQualified attribute anywhere. The WSDL looks like this:
