RequireJS: Module name __ has not been loaded yet for context, but only for SOME, not all

Question

Now I know this question has been asked a million times before, but I still couldn't figure it out.

I have a huge amount of "defines" in various files. Most the time, this works, but a few of my modules are "not loaded for context" sometimes, even-though I put their names in the "define" statement.

===========================

Problem

But, once in a while, I'll randomly get just one of them to "not be loaded for context", eventhough the rest were just fine:

Uncaught Error: Module name "TestPanelView" has not been loaded yet for context: _
http://requirejs.org/docs/errors.html#notloaded 

===========================

Current Fixes

Fix #1 - Using require('');

Instead of

TestPanelView.updateSomething();

I have been doing:

var testPanelView = require('TestPanelView');
testPanelView.updateSomething();

Which works, BUT.. shouldn't it have already been loaded into context since I put it in the header? Why this one? It's the same as all the others!

Fix #2 - Using require([''],function(){});

This also works, but again I'm just doing this one by one and it feels wrong!

Instead of

TestPanelView.updateSomething();

Sometimes I do this:

require(['TestPanelView'], function(testPanelView){
      testPanelView.updateSomething();
});

Failed Attempts #1

TestController.js (Simplified for StackOverflow)

define(['require', 'TestModel', 'TestView', 'SocketLogic', 'Logger', 'TestPanelView'], 
function (require) 
{
var TestModel = require('TestModel')
var TestView = require('TestView');
var SocketLogic = require('SocketLogic');
var Logger = require('Logger');
var TestPanelView = require('TestPanelView');
 return {
    firstMethod: function()
    {
             TestModel.doSomething();
             TestView.doSomethingElse();
             SocketLogic.andAnother();
             Logger.log("hi");
             TestPanelView.updateSomething();
             this.anotherMethod();
    },
    anotherMethod: function()
    {
             console.log("hello");
    }
    }
});

Here I get the "not loaded for context" error again, but this time for all of them.

===========================

Ideas?

I've been manually patching each one that I find like this, which is not happening to all, only some here and there, which feels like monkey patching... I'd like to know what I'm doing wrong here :( Anyone know?

Note: I'm using RequireJS v.2.1.10

Answer 1

Answer to failed attempt #1

define(['require', 'TestModel', 'TestView', 'SocketLogic', 'Logger', 'TestPanelView'], 
function (require, testModel, testView, socketLogic, logger, testPanelView) {
    var firstMethod = function() {
             testModel.doSomething();
             testView.doSomethingElse();
             socketLogic.andAnother();
             logger.log("hi");
             testPanelView.updateSomething();
             this.anotherMethod();
    };
    var anotherMethod = function(){
        console.log("hello");
    }
 return {
    firstMethod: firstMethod,
    anotherMethod: anotherMethod
});

And don't forget, the opening curly bracket must come after the ending round bracket of the function in the same line.
