Invoking Sling Servlets from AEM xtype widgets

You can create an Adobe Experience Manager (AEM) custom component that contains a TreePanel xtype object that displays tree-structured data, such as a data result set that contains JCR data. TreePanel is an instance of CQ.Ext.tree.TreePanel. For information, see CQ.Ext.tree.TreePanel.

You can invoke a Sling Servlet to populate the TreePanel object. That is, the TreePanel object displays the data that is retrieved from the AEM JCR by using a Sling Servlet. The data that is displayed within the TreePanel can be expanded or collapsed by clicking on it.

The TreePanel lets an AEM author view the data that is returned by the Servlet, as shown in the following illustration.
