    Module Interface error


      Hey guys,

           I am having trouble passing data between main app and module created in different project.  In my Flash Builder I have two projects 1. main app and 2. a login module.  I have an interface in login module that I want to use to communicate between module and app. 


           My question is it even possible?  Any example I found so far have modules and app in the same FB project, so main app can just import inteface using

            [code] import com.module.interface.InterfaceName[/code]


          But in my case I can't use the statement above.  How can I communicate using inteface between app and module or module and module when each are their individual projects.  I want to avoid any hard dependencies if possible.


          So far I have been following this example, is there another example that someone can point me too..

          Why can’t you use the import statement?  Point the source-path to the other project (or build a library project to do it “correctly”)

            Hi harUI, can walk me through how to build a library project?  I don't know what you are asking me to do here.


            Here is what I have in FB 4.5

               MainApp (project 1)

               Login (project 2)

                 I have configured this to produce output in /MainApp/assets/modules

                 No html is produced


            Is there anything else I need to do?


              In my MainApp I have

                  <mx:ModuleLoader id="loginMod" url="assets/modules/User.swf" ready="applyUserModSettings(event)"/>


            and applyUserModSettings looks as follows.


            private function applyUserModSettings(event:ModuleEvent):void{

                            var ichild:* = loginMod.child as IUserInterface;

                            if (loginMod.child != null){

                                ichild.setServiceEndPoint = _util.endpoint;




            Here IUserInterface is interface class in Login project com.modules.IModuleInterface

              Create a Flex Library project.  Put the interface class in the source for that project.  Set Project References to that library project from the two other projects.

                Hey harUI,

                    This would mean that for every module I want to create I will have to create 2 projects.  Is this the only way, other than creating all modules under mainapp?

                  I hope all of your modules have something in common, otherwise you are going to have to manage a ton of interfaces and you don’t have as good an abstraction boundary.  If you can define a few interfaces that all modules respond to, then all those interfaces would go in the shared library.

                    Hey harUI,

                       Yes that exactly what I though off later at night.  I can keep all my interfaces under one library and share that lib across all modules.  Thanks for you help on this.
