David,
I see this issue has been addressed already on the Intalio blog/support site. It relates, as I suspected, to rough edges between BPMN and BPEL where attached events (‘faults’) and transactions are concerned. While not perfect, Intalio is I believe the only BPMS that even attempts to implement BPMN compensation, so the fact they do not do it exactly by the book might be forgiven. In my earlier training and writing, I tended to use the compensation end event, but now in my BPMN training I focus instead on the Cancel event, which has more well-defined transaction boundaries and throw-catch semantics, and probably a better match for BPEL.

Time has passed but exception handling still does not seem to be much clearer. I ‘borrowed’ your drawing for my post here http://davethinkingaloud.blogs.....es-of.html . Should the compensation end events be treated as signalling a failure condition? I think they should, but in Intalio they must be in an exception flow. The BPMN spec does not help me much here.

The last paragraph hits the nail on the head and drives it home in one stroke!
BPM tools, in theory are excellent, but only to the extent that the process being mapped is FULLY understood and replicated by the tool! Companies need to make sure that they have competent “Process Mappers” to translate to the BPM tool effectively. Where do I sign up for training?
