[news.eclipse.technology.bpel-designer] Designed Process doesn't run: er

[Dominik@xxxxxxxxx (Dominik Pich)]

I have written a BPEL process... a simple one:

a) retrieveInput
b) buildInvokationMessage (assign)
c) InvokePartner
d) buildAnswerMessage (assign)
return output

I can deploy my process into ODE ok
but for some reason my assign b doesnt work... 
log of ODE says:
....
ERROR - GeronimoLog.error(104) | Assignment Fault: 
{http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure,lineNo=30,faultExplanation=No 
results for expression: {OXPath10Expression /tns:CompanyCode}
....

the relevant xml parts follow:
BPEL:
1
       <bpws:variable messageType="tns:getValueInUSDollarRequest" 
name="stockRequest"/>

2
           <bpws:copy>
               <bpws:from part="payload" variable="input">
                   <bpws:query 
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[/tns:company]]></bpws:query>
               </bpws:from>
               <bpws:to part="parameters" variable="stockRequest">
                   <bpws:query 
queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[/tns:CompanyCode]]></bpws:query>
               </bpws:to>
           </bpws:copy>


wsdl of partners datatype:
           <xs:element name="getValueInUSDollar">
               <xs:complexType>
                   <xs:sequence>
                       <xs:element minOccurs="0" name="CompanyCode" 
nillable="true" type="xs:string"/>
                   </xs:sequence>
               </xs:complexType>
           </xs:element>
