AS3 - Loader class problem tracing the swf (document class)

Question

Hello,

I am using the Loader class to load 3 external swfs:

1. sharedTopics.swf (does not have a document class)
2. fonts.swf (document class is FontManager)
3. main.swf (document class is Main)

The same loader is used to load all 3 assets.

__assetLoader = new Loader(); 
var urlReq:URLRequest = new URLRequest(target.path);
__assetLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, this.preloadProgress);
__assetLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, this.assetCompleteHandler); 
__assetLoader.contentLoaderInfo.addEventListener(Event.INIT, this.assetInitHandler); 
__assetLoader.load(urlReq);

In the complete handler, I add the loader content to a movie clip then trace out a variable:

var swf:DisplayObject = __assetLoader.content;
Debug.doTrace("Shell:: assetCompleteHandler():: content " + swf);
__app.addChild(MovieClip(swf));

When the sharedTopics, fonts and main swfs (respectively) are loaded I get the following trace statements:

Shell:: assetInitHandler():: evt.currentTarget.content [object MovieClip]
Shell:: assetInitHandler():: evt.currentTarget.content [object FontManager]
Shell:: assetInitHandler():: evt.currentTarget.content [object Main__Preloader__]

I would expect that the last trace statement would look similar to '[object Main]' which would be the name of the document class however, instead the content is the loader. Any ideas as to why this is happening?

In a later function I try to call the init function of the Main class and get the following error:

Error #1069: Property init not found on classes.Main__Preloader__ and there is no default value.

I hope this is explained clearly.

Thanks in advance,

Mike

It looks like main.swf wasn't intended to be loaded indirectly as you're attempted to do. zeh has a point , Main could be a child of the SWF...
If this is the case (and it looks like it is), you should have a look at Main.as , find the instance of Main_Preloader and retrieve the url it is loading and load this instead... or try to simply bypass Main_Preloader or/and re-implement it within your AssetLoading class.

The culprate was the TLFTextField. By default, in CS5, the 'Library path' (found in ActionScript3.0 Settings > Library Path) items are set to be Runtime Shared Libraries and use a default preloader, so by changing the 'Default Linkage' to 'Merged into code' you do not have to worry about externally loading these libraries...
