Inheriting Modules with GWT - Source Code Not Found

[Perry Terrance]

I am trying to figure out why GWT keeps telling me why it can't find the source code for my auxiliary module.

My current project breakdown is this:

Module 1 (Primary) has the Entry-Point.
Module 2 (Auxiliary) has no Entry-Point and I'm using only its custom ContentPanel classes.

Module 1 (Primary)

<?xml version="1.0" encoding="UTF-8"?>
<module>
  <inherits name='com.google.gwt.user.User'/>
  <inherits name='com.google.gwt.user.theme.standard.Standard'/>
  <inherits name="com.extjs.gxt.ui.GXT" />
  <inherits name="com.myproject.module2" />
  <entry-point class='com.myproject.primarymodule'/>
  <source path='client'/>
</module>

Module 2 (Auxiliary)

<?xml version="1.0" encoding="UTF-8"?>
<module>
  <inherits name='com.google.gwt.user.User'/>
  <inherits name='com.google.gwt.user.theme.standard.Standard'/>
  <inherits name="com.extjs.gxt.ui.GXT" />
  <source path='client'/>
</module>

In the code sections of Module 1, I make a call of one of the custom classes to Module 2, but it breaks in the program with the "Source Code Not Found - Are You Sure You Inherited?" message.

I've been scratching my head on why it's saying this - when I clearly was inheriting Module 2's XML.

In fact, if I did included a Entry Point into Module 2, I can run Module 2 as its own standalone GWT application with no problems whatsoever...

So what exactly is going on?
