Hi John,
I launched this workflow definition within a clean install of ruote-
rest:
class Test0 < OpenWFE::ProcessDefinition
sequence :on_cancel => "exit" do
participant :ref => "alpha"
participant :ref => "bravo"
end
process_definition :name => "exit" do
participant :ref => "charly"
participant :ref => "zulu"
end
end
At alpha or bravo stage I just cancel the workflow. Then, a new
subprocess called 'exit' is started
and workitem is delivered to participant charly. As far as I see, the
new subprocess is given a new
id which is the old one (main process) plus ".0" so it looks similar
to: 20091019-godepoyoyu.0
Then I GET /processes and see that there is still a process with id
'20091019-godepoyoyu', but the name
has changed to 'exit'. I expected to see the new id '20091019-
godepoyoyu.0'. Then I do a GET on that
process (GET processes/20091019-godepoyoyu) and shows up the following
error:
undefined method `each' for nil:NilClass

It seems that the workflow representation hasn't been created
correctly or the reference to it is wrong.
It's something a bit weird because workitem 'charly' is correctly
created, and I'm able to
do GET /expressions/20091019-godepoyoyu and see that there are
environment (context for 'exit',
process definition (definition for 'exit') and participant ('charly')
expressions.
Thanks for your help and tips.
Best regards.
Gonzalo.
