Hello Wes,
quick initial reply to your set of questions.
There is some documentation about this at
http://ruote.rubyforge.org/definitions.html
Your process definition is not parsed by the workflow engine, it's Ruby that is
interpreted and generates a Ruote syntax tree.
Thus :
require 'rubygems'
require 'ruote'
pdef = Ruote.process_definition :name => 'test' do
cursor do
participant 'koached'
'${message}' == 'STOP' ? _break : rewind
end
end
p pdef
# => ["define", {"name"=>"test"}, [["cursor", {}, [["participant",
{"koached"=>nil}, []], ["rewind", {}, []]]]]]
when "pdef = ..." is called the Ruby code is interpreted to generate the
process definition.
Your process definition is thus equivalent to
pdef = Ruote.process_definition :name => 'test' do
cursor do
participant 'koached'
rewind
end
end
Because '${message}' == 'STOP' is never true.
The right way to write that is
pdef = Ruote.process_definition :name => 'test' do
cursor do
participant 'koached'
rewind :unless => '${message} == STOP'
end
end
See
http://ruote.rubyforge.org/exp/cursor.html
http://ruote.rubyforge.org/common_attributes.html
Now preparing the answer to the rest of your questions.
