Hi Gonzalo,
you have a point, process variables are kept to the engine and not
propagated to [external] participants. Makes sense.
If anyway you'd like to access variables from a custom participant
(that includes the LocalParticipant mixin), you can do something like
---8<---
class MyParticipant
include OpenWFE::LocalParticipant
def consume (workitem)
fe = get_flow_expression(workitem)
puts fe.lookup_variable("toto") # <---
reply_to_engine(workitem)
end
end
--->8---
BlockParticipant instances do include LocalParticipant, so
get_flow_expression(wi) is available to them.
Best regards,
