    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() {

-    //  We know that we want Field's events to bubble directly to the FormPanel.
