Enables events fired by this Observable to bubble up an owner hierarchy by calling +this.getBubbleTarget() if present....

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 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.
