Right, but that would only be evaluated when I click the link, whereas I would like the value to be shown when the list page is shown. For example, in a list of entities I'd like to show next to it the result of a query (i.e. that value isn't stored as a property of the entity, but is evaluated as a result of a query). I can't see how to get them all to display on the list page. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4019416#...
