I've hit a very complicated brick wall

Question

I'm sorry that I can't be more descriptive in my title, but I think I stuck my neck too deep and now I can't tell what is not working. I'm going to atempt to be as clear and concise as possible in my explanation, but sorry if I do something completely wrong or don't understand it fully.
Basically, what I am trying to do is load a bunch of .swf files that each extend the class "Plugin" from a folder called "plugins", and then execute specific code from them at specific times.To do this properly, I'm making a test plugin that is using a .swc library from the main program to extend "Plugin". Whenever I want to instantiate something that extends "Plugin", I have to give it a reference to my main program. However, here is where the problem occurs: when I try to load and then instantiate the plugin, I get an error saying that my main class is not my main class:
TypeError: Error #1034: Type Coercion failed: cannot convert me.bleachisback.cocmod::CoCMain@51b31f1 to me.bleachisback.cocmod.CoCMain.
I've been trying to fix this problem for the past week, and I just can't figure it out. I have a feeling it might have something to do with how I use the .swc file, but I can't tell if that is true/how to fix it because there is barely any documentation out there on it, especially in normal Flash and not Flash Builder.
Below is my source and how I attempted to get it to work:
https://mega.co.nz/#!Pdtn2SiB!ISszSDdGkaZyw6HB1ntRaVD2kckmnAxDeGsMTqS9SVw (A rar file containing my source)
There are 10 main files in the rar:
System/CoCMod.fla - The fla file for the main program
System/CoCMod.swc - The swc file for the main programe, and the library my plugin is using
System/CoCMod.swf - The swf for the main program
System/me/bleachisback/cocmod/CoCMain.as - The main class for the main program
System/me/bleachisback/cocmod/Plugin.as - The "abstract" class that every plugin should extend
System/plugins/TestMod.swf - The swf for the plugin, same as below. Does not do anything unless loaded by the main program.
Test Mod/TestMod.fla - The fla file for the plugin. Has actionscript on frame 1.
Test Mod/TestMod.swf - The swf for the plugin, same as above.
Test Mod/main.xml - Embedded into TestMod.swf, contains information about the mod.
Test Mod/plugin/bleachisback/testPlugin/TestMain - The main class for the plugin - extends Plugin.
This is how I export the .swc file (in CoCMod.fla):
And this is how I reference it in TestMod.fla:
What should happen is just a simple "blah" appears in the console, but for as few lines of code as I have, it doesn't want to work. Can someone tell me what I'm doing wrong?

Answer 1

I assume you mean the setup of my classes?
I now have a CoCMod class which is the main document class of my program: it makes an instance of CoCMain and then loads all of the plugins initialising them with the instance of CoCMain that I created:
    package me.bleachisback.cocmod {
        import flash.display.Loader;
        import flash.display.MovieClip;
        import flash.filesystem.File;
        import flash.events.Event;
        import flash.net.URLRequest;
        import flash.system.ApplicationDomain;
        import flash.system.LoaderContext;
        public class CoCMod extends MovieClip {           
            public function CoCMod() {
                loadPlugins(new CoCMain());
            private var pluginFolder:File = new File(new File("app:/plugins/").nativePath);
            private function loadPlugins(main:CoCMain):void {
                //For first run, make sure plugins folder exists
                //Then load every swf inside it
                if(!pluginFolder.exists)pluginFolder.createDirectory();
                for each(var file:File in pluginFolder.getDirectoryListing()) {
                    if(file.extension == "swf") {
                        var loader:Loader = new Loader();
                        var url:URLRequest = new URLRequest(file.nativePath);
                        loader.load(url, new LoaderContext(false, ApplicationDomain.currentDomain));
                        loader.contentLoaderInfo.addEventListener(Event.COMPLETE, pluginLoadingComplete(main));
            private function pluginLoadingComplete(main:CoCMain):Function {
                return function (e:Event):void {
                    var plugin:Object = new e.target.content.mainClass();
                    var desc:XML = new XML(new e.target.content.description);
                    trace(e.target.applicationDomain == ApplicationDomain.currentDomain); //outputs false
                    plugin.initialise(main, desc.name[0], desc.description[0], desc.version[0], desc.author[0]);
                    plugin.onEnable();
                    plugin.onDisable();
The CoCMain class is relatively unchanged, except for the parts I moved over to this class.
I'm mostly confused as to why, when I specifically tell it to load into ApplicationDomain.currentDomain, the later trace outputs as false.
