Use a link-report to make sure none of the classes in the module are being liked into the main app. Lots of folks have been doing things like:
Var myModule:MyModule = MyModule(moduleInfo.factory.create() Instead of using an interface. This actually links MyModule into the main app, defeating the purpose of modules, and in Flex 4, will mess up the style lookup.

After googling a lot of combination of terms, I was able to finally get some answers regarding problems that seem to come up while trying to develop a modular application, but, sadly, I am not 100% sure what the Adobe person was talking about. The error always centers around the mysterious error: 'ArgumentError: Error #2004: One of the parameters is invalid. at flash.display::Graphics/drawRoundRect()...' More often than not it revolves around a <s:Button> but I just got the same error on a layout that has no buttons. This time it seems to revolve this time be a <s:BorderContainer> since when I swapped it out from a <s:Group> (which worked fine) it started throwing errors. My question to the group is how to manage loading Modules from the application and not throw errors? Why does this happen when it never did it in 3.4. I read it has to do with Style references with the main application, but, again, I don't know exactly what that means or how to fix it. Since it seems to come up in the other posts I could find, I have an Application that, based on a log in and the user's 'accountType', loads a modules for that user's portal type. I use this to load the modules, which seems to be pretty stock, and it works fine for the loading and adding of different modules throughout the application.: private function loadModule(path:String):void { modLoader = ModuleManager.getModule(path); modLoader.addEventListener(ModuleEvent.ERROR, modErrorHandler); modLoader.addEventListener(ModuleEvent.READY, modReadyHandler); modLoader.load(); } private function modErrorHandler(e:ModuleEvent):void { Alert.show("Module did not load correctly", "Module Loading Error"); } private function modReadyHandler(e:ModuleEvent):void { this.removeAllElements(); this.addElement(modLoader.factory.create() as IVisualElement); } Any ideas why I get that error when loading modules? How can I fix it? Does ANYONE know why that error is thrown? -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui
