Best practice

Structure

We are in transation from an old to a new API. Old code use captial letters “GO.*” namespaces. New code uses small letters “go.*”.

The new API can be found in the following folders:

go/modules/<package>/<module>/views/extjs3/*
go/core/views/extjs3/*

Extending

When extending components with Ext.extend() always override initComponent and not the constructor:

go.modules.pkg.mymodule.MyComp = Ext.extend(Ext.Panel, {
  initComponent: function() {
    go.modules.pkg.mymodule.MyComp.superclass.initComponent.call(this);

    //Do your initialization here
  }
});

Core overrides are put in views/Extjs3/javascript/overrides.js
