Class naming and namespace

[Dr. Flink]

I having some problems with calling Ewa.Customer.CustomerGrid.init, from Ewa.Customer.
When the user clicks a button this will call Ewa.Customer.activate() and it will call Ewa.Customer.CustomerGrid.init(). This doesn't work, but if I rename the class to Ewa.CustomerGrid it does.

Could someone please explain what I'm doing wrong and tell me a little bit about namespace or a link that does?

Ewa.Applayout.js

Ext.namespace('Ewa');

// Creates the viewport
Ewa.Applayout = function() {
    ...
    ...
}();

Ext.onReady(Ewa.Applayout.init, Ewa.Applayout);

Ewa.Customer.js

Ext.namespace('Ewa');

// Specifics for the Customer module
Ewa.Customer = function() {
    return {
        init: function() {
            ...
            ...
        },

        activate: function() {
            addActionPanel();
            Ewa.Customer.CustomerGrid.init(); // Here is where I'm having problems
        }
    }
}();

Ext.onReady(function() { Ewa.Customer.init(), Ewa.Customer });

Ewa.Customer.CustomerGrid.js

Ext.namespace('Ewa', 'Ewa.Customer');

Ewa.Customer.CustomerGrid = function() {
    ...
    ...
    return {
        init: function() {
            ...
            ...
        }
}();

What do you mean by doesn't work?

[Dr. Flink]

Evant, thanks for replying.

The function is not found.

Just try debugging like:

alert(Ewa);
alert(Ewa.Customer);
alert(Ewa.Customer.CustomerGrid);
for (var i in Ewa.Customer.CustomerGrid)
   alert(i);

Where abouts does it crash if you do something like that?

[Dr. Flink]

alert(Ewa); // Alerts "[object Object]"
alert(Ewa.Customer); // Alerts "[object Object]"
alert(Ewa.Customer.CustomerGrid); // Alerts "Undefined"

But, if I rename the last object to Ewa.CustomerGrid instead, I will get:

alert(Ewa); // Alerts "[object Object]"
alert(Ewa.Customer); // Alerts "[object Object]"
alert(Ewa.CustomerGrid); // Alerts "[object Object]"
for (var i in Ewa.CustomerGrid)
   alert(i); // Alerts the public functions: "init" and "getGridDataStore"
