John,
It is an intersting exercise...
I am wondering if an automated code generator would not do something like
this:
class BookOrder < OpenWFE:ProcessDefinition
sequence do
customer activity=>'order'
bookstore activity=>'handle order'
bookstore activity=>'place book order'
publisher activity=>'handle order'
_if test => "${f:publisher_reply} == 'order confirmed'" do
branch_1
end
_if test => "${f:publisher_reply} == 'order rejected'" do
branch_2
end
subprocess name="branch_1"
sequence do
bookstore :activity => 'request shipment'
shipper :activity=> 'handle shipment request'
_if test => "${f:shipper_reply} == 'accept shipment'" do
branch_3
end
_if test => "${f:shipper_reply} == 'reject shipment'" do
branch_4
end
end
end
subprocess name="branch_2"
sequence do
bookstore activity=>"alternative publisher'
branch_1
end
end
subprocess name="branch_3"
sequence do
bookstore activity=>'inform publisher'
bookstore activity=>'send bill'
customer activity=>'pay bill'
bookstore activity=>'handle payment'
end
end
subprocess name="branch_4"
bookstore activity=>'alternative shipment'
branch_3
end
end
