OK, let me give you some sample code :
---8<---
require 'rubygems'
require 'ruote'
pdef = Ruote.process_definition :name => 'test' do
cursor do
participant 'alpha'
participant 'bravo'
end
end
$engine = Ruote::Engine.new(Ruote::Worker.new(Ruote::HashStorage.new()))
$sp = $engine.register_participant '.+', Ruote::StorageParticipant
$engine.launch(pdef, 'message' => 'hello')
sleep 1
def p_workitem_info
puts "=== wi info ==="
$sp.each do |wi|
p [ wi.participant_name, wi.fei.wfid, wi.fields['message'] ]
end
end
p_workitem_info
# ok, there is a stored workitem for participant 'alpha'
# let's get it, modify it and push it back to the engine
wi = $sp.first
wi.fields['message'] = 'guten Tag'
$sp.reply(wi)
sleep 1
p_workitem_info
# the engine pushed the workitem up until participant 'bravo'
--->8---
Example output :
=== wi info ===
["alpha", "20100526-bediripagu", "hello"]
=== wi info ===
["bravo", "20100526-bediripagu", "guten Tag"]
Please note that I am not using StorageParticipant#by_wfid. I just pick the
first workitem on the "stack".
When we chatted yesterday, you talked to me about the StorageParticipant#reply :

Look at how I'm using it now. I modify the payload of the workitem (guten Tag)
and then I "let go" of the workitem.
