Zip the project folder rather than its contents, so when someone unzips it, they get one folder, and don't have to create one first. This cost me a Version point on PureMVC
Move the business package under Model. Only a Proxy talks to it, so it shouldn't clutter the namespace at the MVC level. (the CafeTownsend demo has it at that level to make friendly with the Cairngorm folk, but it's not really a recommended practice I'd want to perpetuate with PureMVC. The Model tier is roundly in charge of communicating with remote services if necessary. It could be done inside the Proxy, as with CodePeek, or with a Business Delegate, as you've done here, but either way it will happen within the Model tier.
Further, the Delegate pattern is only really useful to us if multiple Proxies will communicate with the same service the Delegate talks to, although it's not improper to use it if only one Proxy talks to it. It's a good division of responsibility, and I'm not suggesting its removal, only noting here for posterity that a good way to begin an app is to have the service logic inside the Proxy, and then later refactor it into a Delegate at the first call for reuse.
And for the same reason, move the flex/helpers package to model/helpers, since it is the Proxies that use it to parse their data files.
If you wouldn't mind writing a little something about it, I'd love to feature it as a demo. It would be most helpful for people to get a feel for how to turn it into their own thing.
Daniele,I will be happy to help with getting some documentation together and present it here as a demo people can actually get started from. It might be helpful to create a second demo based upon this one, to show the direction someone might take to use it.You can email me at firstname.lastname@example.org
Also, I see you're using Flash Develop. I haven't tried it yet, but it looks good. Did you use Michael Ramirez's PureMVC Project plugin?
