Did some investigation.
To simplify the matter:
Register a storage participant:
storage_participant = engine.register_participant('step_.*',
Ruote::StorageParticipant)
Launch a simple process:
wfid = engine.launch(Ruote.process_definition{sequence{step_one; step_two}})
Now there is a workitem in the storage participant:
items = storage_participant.by_wfid(wfid)
=> [<...>]
Reply this workitem:
storage_participant.reply(items.first)
After some time, there should be a new workitem in the storage
participant, but there isn't.
storage_participant.by_wfid(wfid)
The error is done at writing time as you mentioned in #ruote. See line
91 of cloche.rb:
return true if cur.nil? && doc['_rev'] != -1
cur is nil in this case, as the expression is entered the first time;
the json file has just been touched and is therefore empty. But
doc['_rev'] is 0 (the attribute has been left in the workitem) so the
Cloche#put is left before any writing is done and the json file will be
empty forever...
A possible workaround would be to remove the _rev attribute from the
workitem before replying it to the engine. Should I do this in my
project or should it be done by Ruote itself?
Many thanks again,
Torsten
