Hi, Thanks Alex to inform us. I am adding my same code below.
// Sample Code Start package com { import mx.core.IFlexDisplayObject; import mx.events.CloseEvent; import mx.events.ModuleEvent; import mx.managers.PopUpManager; import mx.modules.ModuleLoader; import spark.components.TitleWindow; public class LoadModule { private var _moduleUrl:String; private var _moduleLoader:ModuleLoader; private var _popUpWindow:TitleWindow; public function LoadModule() { this.openModule(); } private function openModule():void { _moduleUrl = 'testModule.swf'; openModuleAsPopUp(); } private function openModuleAsPopUp():void { _moduleLoader = new ModuleLoader(); if(_popUpWindow == null){ _popUpWindow = new TitleWindow(); _popUpWindow.addEventListener(CloseEvent.CLOSE,moduleCloseHandler); } _popUpWindow.addElement(_moduleLoader); loadModule(_moduleLoader); } private function loadModule(moduleLoader:ModuleLoader):void { moduleLoader.addEventListener(ModuleEvent.READY,onModuleLoadHandler); moduleLoader.addEventListener(ModuleEvent.ERROR,onModuleLoadHandler); moduleLoader.addEventListener(ModuleEvent.SETUP,onModuleLoadHandler); moduleLoader.addEventListener(ModuleEvent.PROGRESS,onModuleLoadHandler); moduleLoader.addEventListener(ModuleEvent.UNLOAD,onModuleLoadHandler); moduleLoader.addEventListener(IOErrorEvent.IO_ERROR,onModuleLoadHandler); moduleLoader.loadModule(_moduleUrl); } private function onModuleLoadHandler(event:ModuleEvent):void { switch(event.type) { case ModuleEvent.READY: onModuleLoadComplete(event.currentTarget.child); break; case ModuleEvent.SETUP: trace("Module Setup"); break; case ModuleEvent.ERROR: trace("Error while loading module"); break; case ModuleEvent.PROGRESS: trace("Module load in progress"); break; case ModuleEvent.UNLOAD: onModuleUnloadComplete(); trace("Unloading module"); break; } } private function onModuleUnloadComplete():void { _moduleLoader.removeEventListener(ModuleEvent.READY,onModuleLoadHandler,false); _moduleLoader.removeEventListener(ModuleEvent.ERROR,onModuleLoadHandler,false); _moduleLoader.removeEventListener(ModuleEvent.SETUP,onModuleLoadHandler,false); _moduleLoader.removeEventListener(ModuleEvent.PROGRESS,onModuleLoadHandler,false); _moduleLoader.removeEventListener(ModuleEvent.UNLOAD,onModuleLoadHandler,false); _moduleLoader.removeEventListener(IOErrorEvent.IO_ERROR,onModuleLoadHandler,false); } private function onModuleLoadComplete(child:*):void { _moduleLoader.addChild(child as DisplayObject); PopUpManager.addPopUp(_popUpWindow as IFlexDisplayObject,FlexGlobals.topLevelApplication as DisplayObject,true); PopUpManager.centerPopUp(_popUpWindow as IFlexDisplayObject); } private function moduleCloseHandler(event:Event):void { _moduleLoader.unloadModule(); PopUpManager.removePopUp(_popUpWindow); _popUpWindow = null; } } } // Sample Code End -----Original Message----- From: Devesh Mishra Sent: 13 November 2013 12:24 To: users@flex.apache.org Subject: RE: One of the parameters is invalid while loading a module Hi Darrel, Good to listen from you. I have attached my action script sample class file in this email. Hope it'll give you a more clarification. Here are my explanation regarding your queries. 1) I have written PopUpManager.centerPopUp() on ready event, because I want to display my popup only when my module get loads completely. Anyways i have already tried with something else i.e. I have tried, just after the initialization of popup window. But still getting same issue. 2) Yes, I am using moduleLoader.addChild(child), after ready event. You'll get more clarification after looking into attached file. Note: Again repeating, this is happening with only one module. Apart from that, I have lots of module in my application and all are working fine. Module where I am getting this issue, it contains only one <mx:Module> and inside module tag, there is one <s:VGroup width="100%" height="100%" gap="10"> That's it inside my module where I am getting error.
