Just make a new project. You'll need to change the root tag from <mx:Application> to <mx:Module> for a MXML project, or change the base class of an ActionScript project from flash.display.Sprite to mx.modules.ModuleBase because FlexBuilder doesn't know about modules directly. (There is some odd asymmetry in the FB project structure in that you can add a new "MXML Application" (which could be a module) to a MXML project - its a many-to-one relationship, but you can't add a new AS Application to an AS project, its always one-to-one.) -rg

I've run into the same problem. How do you use Flex Builder to compile just the module? The only work-around I've found so far is to right-click on the module name in the navigator panel and select Run As Flex Application. This command will create a .swf and .html files for the module and try to load it in the browser (where nothing will display). It's not the best solution and I hope someone posts a better one, but it is all I've found to work so far. I did search through the Flex 2.0.1 help files but did not find anything. Bruce
