I've added some deferred binding magic to load resources from a GWT ClientBundle. If you look at theStore demo, you see what I mean: 1) TheStore bundle: public interface StoreIconBundle extends ClientBundle { @ClientBundle.Source("user_gray.png") ImageResource userGrayIcon(); .... } 2) default bundle declaration: @DefaultBundle(StoreIconBundle.class) public class TheStore implements EntryPoint { ... } 3) Usage in @LoadTool icon declaration: @LoadTool(name = "Users", icon = "userGrayIcon", group = "Administration") public class UserManagement implements WSComponent { ... } For now it's only being used to load tool icons. But it will be extended to support other resources as well (i.e. i18n) in the near future. /Heiko
