    <p>This is the error I am getting in the <em>handleModuleReady</em> function:</p> <pre><code>[Fault] exception, information=TypeError: Error #1034: Type Coercion failed: can not convert MyModule@39b8479 to IModuleInterface. </code></pre> <p>I have an application setup and I have created modules to load at runtime in order to decrease the filesize (as most users will only ever need one of the modules).</p> <pre><code>&lt;!-- maker.mxml --&gt; &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*" layout="absolute" creationComplete="init(event)"&gt; &lt;mx:Style source="css/maker.css" /&gt; &lt;mx:Script&gt; &lt;![CDATA[ //Modules import mx.events.ModuleEvent; import mx.modules.ModuleLoader; import mx.modules.ModuleManager; import mx.modules.IModuleInfo; private var info:IModuleInfo; ... private function init(e:Event):void { info = ModuleManager.getModule("MyModule.swf"); info.addEventListener("ready", handleModuleReady); info.addEventListener("error", handleModuleError); info.load(ApplicationDomain.currentDomain); } private function handleModuleReady(moduleEvent:ModuleEvent):void { var ichild:IModuleInterface = IModuleInterface(moduleEvent.target.factory.create()); if (ichild != null) { //call class functions here via ichild object } else { trace("Something has gone wrong."); } } ... &lt;/mx:Script&gt; ... </code></pre> <p>I have created the IModuleInterface class (IModuleInterface.as), and the MyModule.mxml file compiles without issue, but I continue to get the typecasting error despite trying a variety of potential solutions such as loading the module through ModuleLoader, ModuleManager, and most recently setting the applicationDomain.</p> <p>Please tell me if you know how to fix this. The rest of the internet doesn't. Trust me, I've looked.</p> <p>If relevant, the interface looks something like this.</p> <pre><code>//IModuleInterface.as package { public interface IModuleInterface { function getSomeClass():Class; function getSomeArray():Array; function getSomeInt():int; } } </code></pre>

    1. COSilly question, but I assume the MyModule implements "IModuleInterface" correctly?

    2. COIt "implements IModuleInterface" in the <mx:Module> tag. Is there something additional it needs to do to be correct?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
