Hello Otis,
Have you check the posibility to use Llblgen objects in Flex, and have a special version to make objects specially for that?
I have used the objects using SelfService and modified some code and worked great in conjuction with WebOrb (http://www.themidnightcoders.com/weborb/dotnet/). I modified the connection string and putted on the code. I used Interbase 7.1 and all my stored procs where available from my Flex app.
I saved a lot of time, however I would like to know if we can use more features of Llbl, probably generating by hand some clasess will work, but if Llbl can have that will be Great.
I even saw an eseminar from adobe and they presented Llblgen as an option.

If you plan to have llblgen for Flex we will be glad to help and will be Great.
