Hi John,
I was basically trying to get it running.. Now, I know what should go
inside the process definition.
So, I have created a user pranav and a process definition -
OpenWFE.process_definition :name => 'sample' do
sequence do
pranav
end
end
Once I launch this process definition and login as pranav, I see it
in /workitems but I don't get a proceed button..
Im missing something conceptually fundamental.. Please help..
Pranav
