I am loading a content SWF into a container and I want the content SWF to exist in a child application domain to the container. Therefore, the structure should look like:

[system] -\> [container] -\> [content1]  
[system] -\> [container] -\> [content2]  
…

In my container SWF I load the content SWF with:

```auto

_newDomain = new ApplicationDomain(ApplicationDomain.currentDomain);
var ldrContext:LoaderContext = new LoaderContext(false, _newDomain);
_swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoad);
_swfLoader.load(swfRequest, ldrContext);

```

Then in my content SWF I added the following code to verify that the application domains were being setup correctly:

```auto

var parentDomain:ApplicationDomain = ApplicationDomain.currentDomain.parentDomain;
if (parentDomain == null)
{
     trace("Content is running on its own, no parent domain");
     return;
}

```

That if-statement is being triggered, meaning the content does not recognize the existence of a parent application domain.

Where am I going wrong here?
