I'd use a CellList or CellTable in the view, so all you'd have to do
is to give the view the data and a ValueUpdater.
If you're not using GWT 2.1, I'd nevertheless follow this approach:
i.e. give the view a list of things to display, and a callback/
delegate to be informed when the user clicked a link, provided you
want to be notified back in this case (it could also take the form of
getting a HasSelectionHandlers from the view and listening to
SelectionEvents, it depends how you're "doing MVP").
