Hi, did you ever figure this out? I'm trying to do the exact same thing now except with Flex 4 and ColdFusion9
Sort of. I found this article below that helped me to connect to the remote CF server using MXML. It seems that you have to create a regular project in Flex with Aplication Server Type set to None and connect to CF using the endpoint attribute of the RemoteObject MXML tag or via AS.
However I found out after getting error using the AS3 code to use the endpoint property that
mx.rpc.remoting.RemoteObject does not support the "endpoint" property
whereas mx.rpc.remoting.mxml.RemoteObject does. See link below
So I had to change my AS3 code by adding a new channel to my RemoteObject using a code similar to the one on the link below (Note that this code uses PHP, when I instantiate myRemoteObject, I do so informing that the destination is "ColdFusion" [new RemoteObject("ColdFusion")], so no need to set destination as in the code on the link below
I hope that helps you.
