Better way to call superclass method in ExtJS

Question

All the ExtJS documentation and examples I have read suggest calling superclass methods like this:

MyApp.MyPanel = Ext.extend(Ext.Panel, {
  initComponent: f         


        

Answer 1

I think this is solved in ExtJS 4 with callParent.

Ext.define('My.own.A', {
    constructor: function(test) {
        alert(test);
    }
});

Ext.define('My.own.B', {
    extend: 'My.own.A',

    constructor: function(test) {
        alert(test);

        this.callParent([test + 1]);
    }
});
