Class CQ.Ext.list.Sorter

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by CQ.Ext.Components to bubble events to owner Containers. See CQ.Ext.Component.getBubbleTarget. The default implementation in CQ.Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

CQ.Ext.override(CQ.Ext.form.Field, {
    //  Add functionality to Field's initComponent to enable the change event to bubble
    initComponent : CQ.Ext.form.Field.prototype.initComponent.createSequence(function() {
        this.enableBubble('change');
    }),

    //  We know that we want Field's events to bubble directly to the FormPanel.
    getBubbleTarget : function() {
        if (!this.formPanel) {
            this.formPanel = this.findParentByType('form');
        }
        return this.formPanel;
    }
});

var myForm = new CQ.Ext.formPanel({
    title: 'User Details',
    items: [{
        ...
    }],
    listeners: {
        change: function() {
            // Title goes red if form has been modified.
            myForm.header.setStyle('color', 'red');
        }
    }
});
