Subject RE: One of the parameters is invalid while loading a module
Date Wed, 13 Nov 2013 08:07:25 GMT
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

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.
