Subject Re: BPEL - Assignment selectionFailure
Date Fri, 02 Feb 2007 11:17:52 GMT

Resolved : the right syntax is :

<assign name="assignPoRequest">
   <copy>
    <from xmlns:etnic="http://services.etnic.be">
     <literal>
      <etnic:detailPoAvecAdresse>
       <ai_ns_po_id xmlns=""/>
      </etnic:detailPoAvecAdresse>
     </literal>
    </from>
    <to>$requestPo.parameters</to>
   </copy>			 
   <copy>
    <from xmlns:tns="http://etnic.bull.com">$request.p/tns:poId</from>
    <to
xmlns:etnic="http://services.etnic.be">$requestPo.parameters/ai_ns_po_id</to>
   </copy>
  </assign>
