Description

Steps to reproduce:
1. compile and run test file(bug26163.mxml)
2. click "load Module1" button(it tries to load a module M1 which loads another module: M2).
3. when sub module UI(M2) shows up, click "compute" button

Actual Results:
receive RTE:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

The issue is after module(M1) loads sub module(M2), when it tries to get the module instance with statment like this:
sm=assetModule.factory.create() as SimpleModule;

it returns null, however assetModule.factory.create() returns [object SimpleModule].

Expected Results:
no such error.

Workaround (if any):
no try to convert IModuleInfo.factory.create(), not sm=assetModule.factory.create() as SimpleModule;

instead use sm=assetModule.factory.create(); then access methods of SimpleModule.
