Yes, or build a shell app that loads the module.
BTW, while modules are smaller and faster than sub-applications, they are also more tightly bound as the must use interfaces to communicate with the loading application.. This means that, over time, as your application grows, if your app is comprised of modules, you'll probably need to recompile all of them if you move the main app to a later version of Flex. The same may not be true of sub-applications. While they are fatter, it may be possible in a future release of Flex to make it so they have no tight coupling to the loading application and thus, if your app is comprised of sub-applications, you won't necessarily have to recompile every sub-app. Of course, none of that truly matters now as in order to break tight-coupling we'll probably require that you re-compile all of your pieces as sub-applications on that future version of Flex so you are protected as you go forward. It is unlikely that anything you compile in the interim will work with future versions of Flex. But I wanted to warn you and anybody else who cares that the future of handling applications where it is impractical to recompile everything onto a single version of Flex is probably going to involve sub-applications and not modules. -Alex ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Nate Pearson Sent: Monday, May 12, 2008 2:18 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Working with modules I'm building an application with multiple modules. Each module is a different project in flex builder. I have a main application project that each module compiles a swf to. I want to be able to run each module by it's self to develop/debug it. I can't figure out how to do this. My module projects start out as <mx:application> but when I change it to <mx:module> I can't run it and get any output (even though it has that green arrow). Maybe I just answered my own question, should I just leave it as <mx:application> until I'm done developing then switch it to a module? Thanks so much for the help, Nate
