I'm trying to get a simple layout working under GWT 2.0 using UiBinder. The layout I'm trying to get is one that mimic Java's BorderLayout in where you can specify different panels in the north, south, east, west and center directions; for that I'm using DockLayoutPanel. I would like to get a header and footer, both with fixed width. The remaining viewport space would be occupied by the widget assigned to the DockLayoutPanel center slot.
