Subject Selection Failure on XPath Expression
Date Sat, 05 Jan 2008 23:12:21 GMT
Hi 
In a bpel process I have an assign:
<bpws:assign name="Assign1">
            
            <bpws:copy>
                <bpws:from>'aString'
                </bpws:from>
                <bpws:to>
                $MyObject.request/ttd:someId
                </bpws:to>
            </bpws:copy>         
 </bpws:assign>

Running under ode I get following error:

****************************************************

         {OXPath10Expression
$MyObject.request/ttd:someId}</faultstring>
         <detail/>
      </soapenv:Fault> 

*****************************************************

-The Variable MyObject is a comlexType defined in own
xsd and ttd is the namespace for this xsd
-whole project is deployed successfully to ode and I
can access the bpel process via soap client
-this query does not help too: 
  <bpws:to part="request" variable="MyObject">
             <bpws:query 
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[/ttd:someId]]></bpws:query>
         </bpws:to>

-This bpel process was runing long time under tomcat
and ActiveBpel engine without any problem       

Thanks for any help
