Re: Making an RPC call from a CellTable ButtonCell in a view (MVP pattern)

MVC-wise I think it's on the fence since it's just throwing an event.
The presenter or the view can be changed without having to change the
delete code on either side.

To update my table on a delete I am passing the index of the row on
the delete event.

** Presenter **

@Override
public void onThingDeleteRequest(ThingDeleteEvent event) {
view.removeThing(event.getIndex(), --numThings);
service.deleteThing(event.getThing(), deleteThingCallback);
}

** View **

@Override
public void removeThing(int index, int numThings) {
dataProvider.getList().remove(index);
tableThings.setRowCount(numThings, true);
tableThings.setVisibleRange(0, numThings);
}

Not sure if those are the correct calls to make on the table but it
works for me. I also am not using paging.
