Currently I am using Flex Builder 3 and RestfulX framework to integrate with Ruby on Rails. Now with Builder 4 adding data centric features there may be an alternative way.
I wonder what it would take and how one would add support for Ruby on Rails to data centric services of Flash Builder 4
Here it talks about a possibility of extending it for Ruby on Rails but provides no link to relevant info.
FB4 DCD supports extensibility through which additional server technologies could be supported. Unfortunately, we have not yet added documentation on this. If you would be interested in building ruby on rails support to FB DCD, please drop me a note at rkrishnaATadobeDOTcom.
