+ voidEnables 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 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');
+ }),
+
+ // 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 Ext.formPanel({
+ title: 'User Details',
+ items: [{
+ ...
+ }],
+ listeners: {
+ change: function() {
+ // Title goes red if form has been modified.
