I'm not sure I see the event logic you're talking about.

Hi there,

I have the same problem as dbronk mentioned 
(see below) in conjunction with Cairngorm 2.2.1.

I always have to dispatch the LoadTestEvent 
twice to make the LoadTestCommand calling 
the moduleReadyHandler-method. here is the 
code:

package com.test
{
   import com.adobe.cairngorm.commands.ICommand;
   import com.adobe.cairngorm.control.CairngormEvent;

   import flash.system.ApplicationDomain;

   import mx.events.ModuleEvent;
   import mx.modules.IModuleInfo;
   import mx.modules.ModuleManager;

   public class LoadTestCommand implements ICommand
   {
      private var moduleInfo:IModuleInfo;

      public function LoadTestCommand()
      {
         moduleInfo = ModuleManager.getModule('TestModule.swf');
         moduleInfo.addEventListener(ModuleEvent.READY,
moduleReadyHandler);
         moduleInfo.addEventListener(ModuleEvent.ERROR,
moduleErrorHandler);
      }

      public function execute(event:CairngormEvent):void
      {
         moduleInfo.load(ApplicationDomain.currentDomain);
      }

      public function moduleReadyHandler(e:ModuleEvent) : void
      {
         trace('SUCCESS');
      }

      public function moduleErrorHandler(e:ModuleEvent) : void
      {
         trace('ERROR');
      }
   }
}

Is there a solution to dispatch the event only once 
to make the Command loading the module?

Thank you,
masu

I'm trying to get something very basic to work with modules. I have
my app and two swf modules (Form1.swf and Form2.swf). Each test
module simply has a couple TextInput fields. I have also extended
Module so I can follow what is going on and I will be adding custom
code later. MyModule extends Module has:

public function MyModule() {
super();
trace("Module constructor");
addEventListener(FlexEvent.INITIALIZE, onInitialize);
}

protected function onInitialize(event:Event) : void {
trace("Module.onInit: " + this.toString());
dispatchEvent(new BaseEvent("moduleLoaded", this, true, true));
} 

Very basic. I want to be notified when the Module is initialized.

When I have the following code inline to a button click which will
load the module it works fine

var moduleLoader : ModuleLoader = new ModuleLoader();
moduleLoader.id = moduleName;
moduleLoader.url = moduleName;
moduleLoader.loadModule();
moduleLoader.addEventListener("moduleLoaded", onModuleLoaded);
moduleStackChild = moduleLoader;
moduleStack.addChild(moduleStackChild);
moduleMap.put(moduleName, moduleStackChild);

My onModuleLoaded function gets called.

Now for the issue. If I take this code and place it into a common
object it no longer works THE FIRST TIME. I have two buttons, one to
load Form1.swf and the other to load Form2.swf. When this code to
load the module is in a separate class, it doesn't matter if I click
button 1 or 2 first. It simply will not work on the first click. 
Second click and beyond work fine. Also, in debug mode, works great
every time. What happens is that the last thing that runs is the
loadModule() command. The constructor on MyModule never executes on
the first execution. Future executions work fine.

I'm hoping I explained this good enough as it is very strange. But I
definitely want to have this function in my util classes and not have
to duplicate the code all over the place.

Suggestions?

Thanks,
Dale
