How can I dynamically populate fields located in a component dialog

[smacdonald2008]

I want to dynamically populate fields located in a component's dialog. For example, i want to invoke a 3rd party web service, retrieve  data and populate a drop-down list with data returned by the service. How can this be achieved?

You can invoke an Adobe Experience Manager (AEM) Sling Servlet to populate fields that appear in AEM component dialog. That is, instead of hard-coding values in JavaScript, you can populate a dialog drop-down using a Servlet's return value (for example, JSON data), as shown in the following illustration.
