+ This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default
+implementation in 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: Ext.override(Ext.form.Field, {
+// Add functionality to Field's initComponent to enable the change event to bubble
+ initComponent: Ext.form.Field.prototype.initComponent.createSequence(function() {
+ this.enableBubble('change');
