当我尝试使用超过 2 个模块加载器时,就会出现我的问题。我的第一个问题是当我尝试使用多个 1 时。您可以在下面看到我的解决方法。我对 Modules 还有些陌生,所以如果我在这里遗漏了一些明显的东西,我不会感到惊讶。让我丧命的是它有时如何工作,但有时却没有?

错误:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at ModuleInfo/completeHandler()[C:\autobuild\3.x\frameworks\projects\framework\src\mx\modules\ModuleManager.as:717]

我的应用程序:

            private function getSwf():String

            }

            private function onModuleUnload(moduleEvent:ModuleEvent):void
            {
                // Had to release in order to get 2 to work, now it breaks on 3
                var info:IModuleInfo = ModuleManager.getModule(getSwf());

    <mx:Canvas>
        <mx:ModuleLoader url="{getSwf()}" id="module" ready="onModuleReady(event)" unload="onModuleUnload(event)" x="50" y="50" width="100" height="100"/>

我的模块:

<?xml version="1.0" encoding="utf-8"?>
<mx:Module layout="absolute" xmlns:mx="http://www.adobe.com/2006/mxml" 
           width="100%" height="100%"
           backgroundColor="0xFF0000">
</mx:Module>

谢谢。
