JBoss Forge uses Metawidget for its UI generation. So to accomplish this you must modify Forge's metawidget.xml configuration file.

Forge actually has 3 Metawidget configuration files: metawidget-entity.xml for viewing/editing screens, metawidget-search.xml for search filters, and metawidget-qbe.xml for generating Java code.

For your purposes, you need to modify metawidget-entity.xml. Specifically you must find the JpaInspector entry...

<jpaInspector xmlns="java:org.metawidget.inspector.jpa" config="JpaInspectorConfig">

...and add a child node...

<hideIds><boolean>false</boolean></hideIds>

That bit should be straightforward. However actually getting your modified metawidget-entity.xml back into Forge is clumsy. At the moment the easiest way is probably to unzip and modify the forge-scaffold-faces.jar itself. Hopefully this will be made cleaner in a future Forge release.
