I'm trying to figure out if it's possible to load map layers in my ArcGIS Flex API flex application via something like a plaintext config file at runtime. Basically, I'm debugging my application in one environment using the public ESRI-provided map layers, and then when I deploy the application, it'll be using an internally-hosted ArcGIS server instance on site. I'd like to be able to let the administrator configure the URIs for the relevant map layers without having to recompile the .swf. Is that doable?Thanks!-Dan
