Notice in the previous illustration, three AEM components are displayed in a LiveCopy page:
A custom component named Echo that display text that a user enters into a CQ dialog
An Image component
A standard Text component
By default, the two standard AEM components have a lock, meaning that these components cannot be modified in the LiveCopy page. However, the custom component can be clicked on and modified, as shown by this illustration.
This custom component should be locked within the AEM LiveCopy page. To successfully lock the custom component, you have to add extra configuration to the custom component (this will be shown later in this development article).
This development article walks you through creating a basic AEM custom component name Echo. All it does is let an AEM user enter a value into a dialog. Then the value is displayed in the AEM web page (this is about as simple of a custom component as you can develop). Then the component is displayed in a LiveCopy page, where it can be modified. Finally the custom component is modified further so that it’s locked within the LiveCopy page.
