Toby Tremayne has put forth some code as to how Bender will generate AS objects and connect to Transfer. This is an early first pass and there will undoubtedly be changes, but I am pleased to see he has pushed this stone forward.
In Transfer, your business objects, their properties and relationships to other business objects are configured in Transfer.xml. Bender takes advantage of this 'single source' for object properties/relationships by consuming the Transfer.xml, creating AS classes based of the configured Transfer objects as well as a wrapper for Remoting to the back-end TransferFactory. I believe Chris Scott called the Bender Architecture a 'Remote Command Factory'.
Looking forward to more posts on Bender. Maybe Toby will come to #CFFlex again so I can Bender his ear. (Todo: Remove Bad Pun)
