Hi,
I
downloaded the Coolite.ux.InputMask and me interested in creating a
plugin to edit values (R$ 324.55 for example). Following the model
of InputMask tutorial and the link:
http://extjs.com/learn/Manual:Intro:Inheritance.
I started a plugin MyCurrency as the code below to test.

MyCurrency.cs

MyCurrency.js

Ext.namespace('Ext.ux.netbox');
/*

*/
Ext.ux.netbox.MyCurrency = function(simbol) {
    var simb = simb.Simbol;
};
Ext.extend(Ext.ux.netbox.MyCurrency, Ext.form.TextField, {
    theDocument: Ext.get(document),
    myCurrencyFn1: function() {
        // etc.
    },
    myCurrencyFn2: function() {
        // etc.
    }
});
Ext.ux.MyCurrency = Ext.ux.netbox.MyCurrency;
I put the plugin on the page and run the error occurs:

Ext.ux.netbox.MyCurrency is not a constructor


Any tips?
Thank you.
Maia.
