 146 <code>this.getBubbleTarget()</code> if present. There is no implementation in the Observable base class.</p>
 147 <p>This is commonly used by Ext.Components to bubble events to owner Containers. See <a href="output/Ext.Component.getBubbleTarget.html" ext:cls="Ext.Component.getBubbleTarget">Ext.Component.getBubbleTarget</a>. The default
 148 implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to
 149 access the required target more quickly.</p>
 150 <p>Example:</p><pre><code>Ext.override(Ext.form.Field, {
 151     <i>//  Add functionality to Field&#39;s initComponent to enable the change event to bubble</i>
 152     initComponent : Ext.form.Field.prototype.initComponent.createSequence(<b>function</b>() {
 153         this.enableBubble(<em>'change'</em>);
 154     }),

 156     <i>//  We know that we want Field&#39;s events to bubble directly to the FormPanel.</i>
