copied!<p>I see a couple issues before getting into the multi-module communication.</p> <p>First, in your changeView() function, you are declaring the variable action and then switching on it. </p> <pre><code>public function changeView():void { var action:String; switch(action) { // action will always be null here. } } </code></pre> <p>Because you don't have a 'default' case in your switch statement(s), parentApplication.switchView will never be called.</p> <p>Also, for the sake of brevity, you can write switch statements like this:</p> <pre><code>switch(action) { case "admin": parentApplication.changeView("admin"); break; case "tv": parentApplication.changeView("tv"); break; case "shop": parentApplication.changeView("shop"); break; // ... etc ... default: // this gets called if action doesn't match anything. break; } </code></pre> <p>Finally, you could save yourself even more typing because your action and module ids are the same, you could do this:</p> <pre><code>public function changeView(action:String):void { parentApplication.changeView(action); } </code></pre> <p>Maybe try those things and then updating your question (also, the XML for your context menus didn't render correctly in your question). That may help the community solve your issue a little easier.</p> <h2>UPDATE</h2> <p>I don't think the problem is in the module communication. I built a simple project that does what I think you're looking for. I've posted the source below.</p> <p><strong>mmodules.mxml</strong></p> <pre><code><?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" implements="interfaces.IApplication"> <mx:Script> <![CDATA[ import mx.core.Container; public function changeView(action:String):void { viewstack.selectedChild = viewstack.getChildByName(action) as Container; } ]]> </mx:Script> <mx:ViewStack id="viewstack" width="100%" height="100%"> <mx:ModuleLoader id="module1" url="views/module1.swf" /> <mx:ModuleLoader id="module2" url="views/module2.swf" /> </mx:ViewStack> </mx:Application> </code></pre> <p><strong>interfaces/IApplication.as</strong></p> <pre><code>package interfaces { public interface IApplication { function changeView(action:String); } } </code></pre> <p><strong>views/module1.mxml</strong></p> <pre><code><?xml version="1.0" encoding="utf-8"?> <mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ import interfaces.IApplication; import mx.events.MenuEvent; import mx.controls.Menu; /** * Dynamically builds a menu. */ protected function showMenu():void { var m:Menu = Menu.createMenu(null, menuData, false); m.labelField = '@label'; m.addEventListener(MenuEvent.ITEM_CLICK, onItemClick); m.show(10, 10); } /** * Handles whenever an item in the menu is clicked. */ protected function onItemClick(e:MenuEvent):void { if(e && e.item && e.item is XML) { changeView(e.item.@action); } } /** * Tells the parent application to switch views. */ protected function changeView(action:String):void { var app:IApplication = parentApplication as IApplication; switch(action) { case 'module1': app.changeView('module1'); break; case 'module2': app.changeView('module2'); break; } } ]]> </mx:Script> <mx:XML format="e4x" id="menuData"> <root> <menuitem label="Module 1" action="module1" /> <menuitem label="Module 2" action="module2" /> </root> </mx:XML> <mx:Button label="Show menu" click="showMenu()" /> </mx:Module> </code></pre> <p>Hope that helps.</p>
