Loading Modules/Runtime CSS into an AIR App

For those planning to load a Flex module into your AIR application from a remote server: take a look at this post before beating your head against the wall with this ambiguous error message Error: Unable to load style(SWF is not a loadable module).

Basically, loaded SWF’s are not allowed to be in the same security domain as your AIR app. Since modules and external styles loaded using StyleManager.loadStyleDeclaration() try to load themselves into the current security domain, an error will be thrown. The only workaround it appears is to bundle those modules with your application when it’s downloaded. Any new modules you want to add to your application at a later time can be downloaded using AIR’s update API via Updater.update().
