Thanks so much. That makes a lot of sense. So I just need to experiment with the data grid height.
I would think using using "*com.google.gwt.user.client.ui.ScrollPanel*" instead would fix this, but it does not. I am still going to play with various height values, but just seemed weird because ScrollPanel implements ProvidesResize.
