How to get the URL of a Flex Module from within the Module when this.loaderInfo is null

Question

I've used ModuleManager to load a Flex Module. When the module is fully loaded I want learn the URL of the swf that contains the class definition from which the module instance was created. I haven't studied the internals of the Flex framework, but I suspect that the IModuleInfo instance's factory.create() is probably calling on applicationDomain.getDefinition() and that might be the reason that this.loaderInfo is null.

Anyhow, how can a Flex Module get the URL from which it was loaded when it was loaded by the ModuleManager and created using the resultant imoduleInfo.factory.create()?
