Subject Re: Problem calling/executing async BPEL Process
Date Sat, 29 Nov 2008 16:58:38 GMT
Hi Daniel,

We'll need your full BPEL deployment bundle to diagnose.  For some reason,
the engine thinks you're doing a process-to-process invocation instead of
calling back the client.    We don't have enough information to tell why.
