title: Why is the Simplified CommonJS Wrapper syntax not working on my Dojo AMD module?
body: <p>Im starting to sort of wrap my head around requirejs and the new Dojo AMD structure, but I have a problem with some early tests:</p>
  
  <p>cg/signup.js:</p>
  
  <pre><code>define(['dojo/_base/fx', 'dojo/dom'], function(fx, dom){    
      return function(){
          this.hidePreloader = function(id){
              var preloader = dom.byId(id);
              fx.fadeOut({node : preloader}).play()
          }
      }
  })
  </code></pre>
  
  <p>This works fine.  In the master cg.js file:</p>
  
  <pre><code>require(['dojo/_base/kernel', 'dojo/_base/loader'])
  dojo.registerModulePath('cg', '../cg')
  
  require(['cg/signup', 'dojo/domReady!'], function(Signup){
          var sp = new Signup();
          sp.hidePreloader('preloader')
  })
  </code></pre>
  
  <p>Bam. Done. However, in using the Simplified CommonJS Wrapper structure:</p>
  
  <pre><code>define(function(require){    
      var fx = require('dojo/_base/fx'),
          dom = require('dojo/dom');
  
      return function(){
          this.hidePreloader = function(id){
              var preloader = dom.byId(id);
              fx.fadeOut({node : preloader}).play()
          }
      }
  })
  </code></pre>
  
  <p>I get an undefinedModule error.  It seems to come from the <code>dojo/_base/fx</code> line, but I don't know why.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>For clarification.</p>
  
  <p><em>index.html scripts</em></p>
  
  <pre><code>&lt;script type="text/javascript" src="js/dojo/dojo.js.uncompressed.js" data-dojo-config="isDebug:true,async:true"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="js/cg.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p><em>cg.js</em></p>
  
  <pre><code>require(['dojo/_base/kernel', 'dojo/_base/loader'])
  dojo.registerModulePath('cg', '../cg')
  
  require(['cg/signup', 'dojo/domReady!'], function(signup){
      signup.testFunc()
  })
  </code></pre>
  
  <p><em>js/cg/signup.js</em></p>
  
  <pre><code>define(['require', 'exports'], function(require, exports){
      var dom = require('dojo/_base/kernel');
  // Any other require() declarations (with very very few exceptions like 'dojo/_base/array throw undefinedModule errors!!!
  
      // without any error causing requires, this works fine.
      exports.testFunc = function(){
          alert("hello")
      }
  })
