Hi Tim, > are you using Cairngorm2 yet?
Yes, we are using Cairngorm2 on a pretty large Flex/ColdFusion project. Our architecture : - ColdFusion MX 7 Standard + Flash Media Server 2 + SQL Server 2005 (we do not plan to use Flex Enterprise Services), - Flash (Flex 2). Frameworks used : - ColdSpring to handle our CFC-based model/service layers, - Model-Glue to handle our CFC/CFM-based view/controller layers for the HTML client, - Cairngorm to handle our AS3/MXML model/view/controller layers for the Flash client. I'm a big fan of those three frameworks : lightweight and powerful. We never used ARP, so I have no opinions on it. As soon as I have some times (maybe this week-end...), I'll write a sample Flex/ColdFusion application (probably, a Cairngorm 2 version of Ben Forta's Phones app). Benoit Hediard PS: Later this year, I also plan to rebuild entirely benorama.com (not updated since 2002 for CFMX launch...), in order to put all the latest Flex2/ColdFusion7 best practices! -----Message d'origine----- De : [email protected] [mailto:[EMAIL PROTECTED] De la part de sufibaba Envoyé : mardi 7 février 2006 23:08 À : [email protected] Objet : [flexcoders] Re: Flex/Coldfusion connectivity test app Thanks for the excellent reply. You saved the day. We do have CF working with Flex. There's also the Phones example on the Adobe Labs site that shows this connectivity. All of this is working fine. The challenge we were having was with the new version of Cairngorm. We have been using ARP for a flash application that is to be migrated to flex2 and we need to get a bit of advice from the creator of Cairngorm -- who is now Adobe, to suggest a best practice example that shows how coldfusion is the "perfect mate" for flex2. The login example that was given is a bit too simplified and also did not include how coldfusion. If Adobe wants to sell coldfusion with flex, then it would be beneficial to demonstrate via examples how things could work together. Anyhow, aside from our wish list to Adobe, Merci Beaucoup for your excellent tutorial and sharing your experiences, especially the bugs. BTW, are you using Cairngorm2 yet? or what type of architecture are you using. P.S. I used your Benorama architecture for a project and was very happy with it. What are your thoughts on Cairngorm and the upcomming ARP3 for flex2.
