Hello,
I try to write a very simple BPEL process with Apache ODE as a Service
Engine into Servicemix.
I have a problem with the assignment operation.
I receive always an error. Here the trace in Servicemix :
-----------------------------------------------------------------------------
ERROR - ASSIGN - Assignment Fault:
{http://schemas.xmlsoap.org/ws/2004/03/business-process/}selection
Failure,lineNo=58
The line number 58 is the copy operation below :
---------------------------------------------------------------------
<copy>
<from xmlns:tns="http://etnic.bull.com";>$request.p/tns:poId</from>
<to
xmlns:etnic="http://services.etnic.be";>$requestPo.parameters/etnic:detailPoAvecAdresse/ai_ns_po_id</to>
</copy>
Here my BPEL process :

The definition of the messages involved in the copy operation wich fails :

Do you have an idea of what is wrong ???
Thanks in advance,
