Hi all,
I'm having a conceptual question on how to achieve the following:

Let's imagine I have a Toolbar:
Code:
MyToolbar = Ext.extend(Ext.Toolbar, {
    initComponent : function() {
        this.items = this.getToolbarItems();

        MyToolbar.superclass.initComponent.call(this);
    },

    getToolbarItems: function () {
        return [{
            text: 'Original Button'
        }];
    }
});
But then I have another file that wants to augment this Toolbar adding an extra button. If I override the getToolbarItems then I lose the original item that was there:

Code:
Ext.override(MyToolbar,{
    getToolbarItems: function () {
        return [{
            text: 'Additional Button'
        }]
    }
});
This will result in having a toolbar just with "Additional Button" instead of the 2 buttons.

I've read the following:

But I don't really like the solution of closures because then I cannot incorporate the change inside of a component...

Is this the only way to achieve what I want?
