Including a data Store makes the app not load - extjs

Question

I can't get my application to work using MVC architecture.
Here is the code:
app.js
Ext.application({
name: CONFIG.APP_NS,
appFolder: '../js/app',
autoCreateViewport: true,
/*
models: ['User'],
stores: ['Users'],
//*/
controllers: ['Main', 'Tab', 'Import', 'Export', 'Predict', 'Admin']
});
Import.js (controller)
Ext.define(CONFIG.APP_NS+'.controller.Import', {
extend: 'Ext.app.Controller',
//stores: ['Users'], //Uncommenting this makes the application not load at all
models: ['User'],
views: ['Import.Window', 'Import.Toolbar', 'Import.Grid'],
init: function(){
...
},
...
});
User.js (model)
Ext.define(CONFIG.APP_NS+'.model.User', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'int'},
{name: 'username', type: 'string'},
{name: 'password', type: 'string'},
{name: 'salt', type: 'string'},
{name: 'firstName', type: 'string'},
{name: 'lastName', type: 'string'},
{name: 'email', type: 'string'},
{name: 'admin', type: 'boolean'},
{name: 'authenticated', type: 'boolean'}
],
hasMany: {model: CONFIG.APP_NS+'.model.Roles', name: 'roles'},
proxy: {
type: 'ajax',
url: 'model/users',
reader: {
type: 'json'
}
}
});
Ext.define(CONFIG.APP_NS+'.model.Roles', {
extend: 'Ext.data.Model',
fields: [
{name: 'role', type: 'string'}
],
belongsTo: CONFIG.APP_NS+'.model.User'
});
Users.js (store)
Ext.define(CONFIG.APP_NS+'store.Users', {
extend: 'Ext.data.Store',
requires: CONFIG.APP_NS+'.model.User',
model: CONFIG.APP_NS+'.model.User'
});
Grid.js (view)
Ext.define(CONFIG.APP_NS+'.view.Import.Grid', {
extend: 'Ext.grid.Panel',
alias: 'widget.importgrid',
initComponent: function() {
this.store = Ext.create('Ext.data.Store', { //Works fine with the code as it is
model: CONFIG.APP_NS+'.model.User',
proxy: {
type: 'ajax',
url: 'model/users',
reader: {
type: 'json'
}
}
});
//*/
//this.store = Ext.create(CONFIG.APP_NS+'.store.Users', {});
this.columns = [
{header: 'Name', dataIndex: 'username', flex: 1},
{header: 'Email', dataIndex: 'email', flex: 1}
];
this.callParent(arguments);
this.store.load();
}
});
I have tried almost every combination of stores: in different files possible, nothing seems to do the trick. If I do not include the store anywhere, I get the error Object is not a function (or TypeError: Cannot call method 'on' of undefined if defined outside of the initComponent in the view) somewhere in internal extjs files. It seems that even if I copy the structure from the tutorial examples, it still does not work, so I must be missing something.
What am I doing wrong?
Thank you for your time.
EDITS:
I am running this code on Wamp (localhost). The server has both ExtJS4 and Symfony installed and running.
Updated error message.
Fixed a typo in the Model, see comments.

Answer 1

(I see you have the stores commented out in the app.js. Is this intentional?)
I ran into a similar problem.. as soon as i added the store to my app.js and view.js (a grid panel), my app stopped working.
I'm pretty sure I fixed it by adding the stores (all of them) to the controller and the app.js. Ok.. just checked again, and I get a different error message if the store was missing from controller.js: "Uncaught TypeError: Cannot call method 'on' of undefined" (this is on chrome). Slightly different error message.
Also, consider commenting out the this.store.load().. i.e. remove the server data-access variable - (one thing at a time.)

Answer 2

I found the bug.
Users.js (store)
Ext.define(CONFIG.APP_NS+'store.Users', {
extend: 'Ext.data.Store',
requires: CONFIG.APP_NS+'.model.User',
model: CONFIG.APP_NS+'.model.User'
});
First line should be:
Ext.define(CONFIG.APP_NS+'.store.Users', {
I was missing a period before store.
Molecule Man's comment made me recheck all the definitions, thank you.
