We did spike a little counter using Wicket's integration with Atmosphere [4] a couple of years ago, just to push the current time down to the web browser, but we didn't take it any further. There are a couple of ways I can see this requirement might be tackled, but perhaps the easiest would be to provide some sort of Wicket widget (maybe rendered in the footer) that has built-in knowledge of the background command queue, and so which could indicate to the user what the status of their job(s) are. When the user clicks on a job it could perhaps render the persisted Command (or maybe a view model for a simplified UI / could perhaps go to the "target" / most relevant object that has been updated). Interested in your thoughts; we actually have a somewhat similar requirement for Estatio, so would be good to kick around some ideas.
