When we submitted our Flex-ColdFusion example to IFBIN, Flex was in an early beta, which means that the example doesn't work with the final release.
All IFIBIN authors have their signature "Hello World" example. Because what it represents us is the integration of Flex and ColdFusion, we decided that our Hello World needed to have ColdFusion in the mix.
I just updated the example and I am posting it here for download. I will submit the update to IFBIN soon. As you will see, it is very simple, as "Hello Worlds" should be. It shows how to use the RemoteObject tag to communicate with ColdFusion, how to deal with the server response and how to make a simple state transition.
