Thanks Danny, I also found there is a cancel method in Dashboard. But when I cancel a wokitem for alice, bob will still get the job. So I am wondering.....What is the difference between cancel and proceed?

Yes, that's right. And the on_cancel you placed on the parent 'sequence' will
not trigger since the expression that got cancelled is the alice participant
expression, not the sequence expression.

Dashboard#cancel(wfid_or_fei)
cancels a whole process instance (wfid) or only a branch of a process
instance (fei).
StorageParticipant#proceed(workitem)
will "unstore" the workitem and reply with it (and its potentially updated
fields) to the participant expression that emitted it. That usually makes the
flow resume.

I'll cook up something in the Receiver/StorageParticipant that leverages that.
I hope to be done with this work by tomorrow, I'll notify you about it in this
mailing list thread. Stay tuned.

Hello,
I've just added a #flunk method to the storage participant:
