This method handles the 'dragOver event (and is executing):

de.preventDefault();

var dropLocal:DropLocation =
owner.layout.calculateDropLocation(de);

However, the drop indicator is not visible. I set a breakpoint in the code

The preloader is instantiated long before the application. The app’s preloader

Subject: Re: [flexcoders] Inject dependency into Flex application preloader
You can write your code like that, but what code would set those values? None
of the MVC frameworks I know of are running when the preloader is running.
That’s the point of the preloader. It is framework independent and very
lightweight so you can view something while the rest of the frameworks get
downloaded and initialized.
There are two phases to the preloader: download and initialize. You could
probably set something in the initializing phase if you really want to.

RE: [flexcoders] Re: ModuleLoader.child is null
The module loads fine in a simple testbed, but in this particular larger
application context, fails (and it's time consuming/costly debugging, when by
all extents and purposes, it should work). In the end, I can achieve a similar
result with SWFLoader, and cast the result as an interface type...

The ModuleEvent.READY listener is executing, the path is correct.
>> var test:ITest ITest(this._moduleLoader.child);
This was a typo. this._moduleLoader.child is still null here though. I get the
same problem using mx and spark ModuleLoader. So unless someone can spot the
problem, I'm going to use SWFLoader...

Perhaps you're getting an error on load; probably due to the path. Try
adding an event listener for ModuleEvent.ERROR.
Also, this line is missing an equal sign:
var test:ITest ITest(this._moduleLoader.child);
Should be:
var test:ITest = ITest(this._moduleLoader.child);

RE: [flexcoders] Re: ModuleLoader.child is null
>>> var test:ITest ITest(this._moduleLoader.child); // null
The module implements ITest. Regardless, before the module is cast to an
interface, this._moduleLoader.child is null. I read on another thread that the
module 'ready' event may be dispatched before it's ready...

Subject: [flexcoders] Re: ModuleLoader.child is null
In your module code I don't see where it implements
com.storefront.interfaces.controller.ITest. If there is no implementation of
the interface, the child will be null.
