I got this to multiple selection to work properly by adding a ButtonCell adjacent to the CheckboxCell. The code is in Bike Shed. The ButtonCell is also bound to the Selection Model. This takes care of what seem to be two bugs: 1) the CheckboxCell is not firing a setFieldUpdater event 2) the ButtonCell event is not fired correctly. Giving the table something else to do, i.e., with the CheckboxCell, helps the event to propagate correctly.
For the record I also use the Selection Model's selection change listener to inform the presenter that a selection has changed. Lastly, you need to make sure your model implements Comparable. The compareTo, equals, and hashCode have to be well implemented for the selection model to work ok.
