John, after all my attempts on ruote I received a lot of new
information and have a bit mess in mind, so may be I missed
something.
My external participant need to store some result of external call
without replying to the engine and utilize stored information in the
"cancel".
Below is a simple example, which uses some questionable approach for
that. It works, but I'm not sure - it feels not good for me. Tried on
the ruote's "trunk".
------ Participant
def consume( workitem )
#some external work returns an "id"
id = some_external_call()
#now need to store received id for futher use in "cancel"
without replying. Reply will be done by external service.
exp = fetch_flow_expression( workitem )
exp.h.applied_workitem[ 'received_id'] = id
exp.persist_or_raise
end
def cancel(fei, flavour)
wi = Ruote::Exp::FlowExpression.fetch(@context,
fei.to_h).h.applied_workitem
cancel_prev_external_call( wi['received_id'] )
end
--------------------
Best regards, Oleg
