How to Add Listeners to Dialogs in Adobe Experience Manager (AEM): A Comprehensive Guide

In Adobe Experience Manager (AEM), a dialog is a key user interface element that allows content authors to input and configure content. Listeners, on the other hand, are events that can be added to these dialogs to trigger specific actions when certain events occur. This guide will provide you with a systematic process for adding listeners to a dialog in AEM Classic UI.

Key Takeaways

  • Dialogs in AEM provide a user interface for content authors to configure content.
  • Listeners are events that can trigger specific actions in dialogs.
  • Adding a listener to a dialog involves modifying the dialog’s node in CRXDE Lite.
  • Various listener events can be added, such as ‘load’, ‘submit’, ‘beforeSubmit’, etc.

Understanding Dialogs and Listeners in AEM

In AEM, dialogs are the primary way for content authors to input and configure content. They consist of various fields like text, number, pathfield, etc., that take user inputs. Listeners, on the other hand, are scripts that listen for specific events in the dialog. When these events occur, the listener triggers the corresponding action.

Accessing CRXDE Lite

The first step to adding a listener to a dialog is to access CRXDE Lite, which is AEM’s built-in development environment.

Steps to Access CRXDE Lite

  1. Open your web browser and navigate to http://[your_AEM_server]:[port]/crx/de.
  2. Log in with your AEM credentials.

Navigating to the Dialog Node

Once you’re in CRXDE Lite, you need to navigate to the dialog node where you want to add the listener.

Steps to Navigate to the Dialog Node

  1. In the left-hand side panel, expand the /apps node.
  2. Navigate through your project’s hierarchy until you find the dialog node.

Creating a New Node for the Listener

Before you add the listener, you need to create a new node under the dialog node.

Steps to Create a New Node

  1. Right-click on the dialog node and select Create -> Create Node.
  2. Name the node listeners and set its type to nt:unstructured.
  3. Click OK to create the node.

Adding the Listener

With the ‘listeners’ node in place, you can now add the listener.

Steps to Add the Listener

  1. Right-click on the ‘listeners’ node and select Create -> Create Node.
  2. Name the node after the event you want to listen for (e.g., ‘load’, ‘submit’, etc.).
  3. Set the node’s type to nt:unstructured.
  4. Add a new property to the node. Name it xtype, and set its value to listeners.
  5. Add another property. Name it after the event (the same as the node’s name), and set its value to the JavaScript code you want to run when the event occurs.

Saving Your Changes

After adding the listener, you need to save your changes.

Steps to Save Changes

  1. Click the Save All button at the top of the CRXDE Lite interface.

Verifying the Listener

The final step is to verify that your listener is working correctly.

Steps to Verify the Listener

  1. Navigate to the dialog in the AEM authoring interface.
  2. Perform the action that triggers the event you’re listening for.
  3. Verify that the listener’s action is carried out.


Listeners in AEM dialogs provide an efficient way to trigger specific actions based on user interactions. By understanding how to add listeners to dialogs in AEM, you can create more interactive and dynamic experiences for content authors.
