my pdef:
cursor do
user_3 :task => 'doing user_3 stuff...'
echo 'back from participant-implementation...'
user_4 :task => 'doing user_4 stuff now...'
echo 'end of Pdef reached'
end
My registration:
@dboard.register do
participant /^user_/, Klaus::SkilledParticipant
end
My Participant-Impl:
class SkilledParticipant < Ruote::StorageParticipant
include Ruote::LocalParticipant
def on_workitem
puts "partitcipant-name: * #{workitem.participant_name}"
level = workitem.participant_name.match(/^user_(\d+)/)
[1].to_i
puts "level=#{level}"
puts "i am into local Participant now!"
super
reply_to_engine(workitem)
end
end
if i login, say my user-name and launch the process-definition, it
says:
username: user_3
skill-level: 0
registered participant...
user_3> launch
user= user_3
skill= 0
launched process instance 20120509-0739-duduwaja-nazegiku
user_3> my skill level is: 0
do level 0 jobs
do the task now!
partitcipant-name: * user_3
level=3
i am into local Participant now!
back from participant-implementation...
partitcipant-name: * user_4
level=4
i am into local Participant now!
end of Pdef reached
it seems as during launching the pdef, all code from my participant-
implementation will be executed, no matter of sequence or waiting for
the next participant.
if I now ask for workitems, it says:
workitems
N ID PARTICIPANT
TASK
0 20120509-0740-rajobiza-gidogebu 0_0_0_4 user_3 doing
user_3 stuff...
1 20120509-0740-rajobiza-gidogebu 0_0_0_6 user_4 doing
user_4 stuff now...
workitems: 2
I thought the participiant "user_4" can only be executed if
participant "user_3" has his work done...
like a storage-participant does.
My main question is: I do not know where to put the main logic - into
pdef or into implementation - of the participant.
Sorry, but already I Do not understand why the "launch" action
consumes the whole workflows, with all participants without waiting
for a "proceed" action or waiting for the special participant, logged
in.
greetings
Klaus
