Ok , I'll try to give concrete example: I failed on last assign in BPEL description below. Actually I did not fail(no errors), but I do know that last invoke was not completed. Probably because last assign is wrong. My process should connect to WS called Customer and retrieve Complex object as response: My bpel is: | <?xml version="1.0" encoding="UTF-8"?> | <process name="salesOrderCreationBusinessProcess"
