Hello Jim, My specific usecase is:
--------- ----->| Final | ---------- / --------- ...-->| Update |- --------- ---------- \----->| Issue |-->... ^ \ --------- | \ ---------- | \-->| Review | | ---------- | | +------------------+ Update -> Final is guarded by "review_result == 'accepted'" Update -> Issue is guarded by "transitionName == 'update_issue'" Update -> Review is guarded by "transitionName == 'update_review'" On the UI I put up every possible transition. Now if my crazy user chooses Final if review_result != 'accepted' then bang, the process gets finished. No errors, no messages, no exceptions. I already thought of filtering the possible transitions on the UI, but how? transitionName still forces the other conditions to false. A kind of transition-precondition is not available as I know. In this usecase raising an exception and thus not letting any transition to fire fits me perfectly. XPDL would give the options - exception - default exception - otherwise but none of these are implemented in zope.wfmc. I think finishing the whole process is definitely bad behaviour. But what's correct? Please give a hint what should be done.
