Will Flex 4 UI's built in Catalyst be able to hook up to a RoR backend in the way the Flex 3 on Rails 2 is described in Flexible Rails by Peter Armstrong, Manning Publications?
Any pointers to articles from anyone who is doing this yet? I have the Armstrong book, but am tempted to skip it and wait for a book regarding Flex 4 on Rails, but if you can foresee some reason why Flex 4 on Rails won't work, I'll go ahead and tackle Flex 3 on Rails 2.
Backend connection services (RemoteObject, WebService, and HTTPService) have not changed between Flex 3 and Flex 4.
So, everything in the book you have that relates to connecting to the backend is probably still applicable.
Thanks... Thats good to know. Sounds like it is worth the investment of working through Flexible Rails.
