I would do this using your example object public class ExampleFoo extends Foo { | private boolean showClosedObject; | // getters and setters | | public Date getDate() { | if (showClosedObject) { | return super.getDate(); | } else { | return null; | } | } then, your restriction will only be applied if your checkbox is checked. The restriction could just be closedDate < Now() View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4039429#...
