Invalid response state for mex: ASYNC

[Jan Loewe]

Hi all,

I am currently trying to call a simple external web-service using
<invoke> and getting a reply. My service gets called and the reply is
send. I digged into the source a bit and
MessageExchangeImpl.setResponse(Message outputMessage) is called and  as
far as I understand this means, that the message is fine. But then,
later in BpelRuntimeContextImpl.invocationResponse2(String mexid,
InvokeResponseChannel responseChannel), I get a MEX that has no response
attached to it. Am I right, that there should be one, as long as the
MEX-ID is the same? The MEX I get has also its status set to ASYNC, so
the error mentioned in the topic appears. I will attach my BPEL and WSDL
files, maybe I'm just too stupid to understand BPEL.

regards,
Jan
