我浪費了很多時間來嘗試使基本網格工作。我用這個版本庫：基本網格沒有工作
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt</artifactId>
<version>2.1.1</version>
</dependency>
<dependency>
<groupId>com.extjs</groupId>
<artifactId>gxt</artifactId>
<version>2.2.0</version>
</dependency>
我讓所有的例子：http://zawoad.blogspot.com/2009/08/how-to-create-simple-grid-using-gxtext.html 在moduleOnLoad我寫了這個：
@Override
public void onModuleLoad() {
User admin = new User();
admin.setLogin("Admin");
admin.set("login", "admin");
List<User> users = Arrays.asList(admin);
List<ColumnConfig> configs = new ArrayList<ColumnConfig>();
ColumnConfig loginColumn = new ColumnConfig("login", "Login", 100);
configs.add(loginColumn);
ListStore<User> listStore = new ListStore<User>();
listStore.add(users);
ColumnModel cm = new ColumnModel(configs);
Grid<User> grid = new Grid<User>(listStore, cm);
grid.setStyleAttribute("borderTop", "none");
grid.setAutoExpandColumn("login");
grid.setBorders(true);
grid.setStripeRows(true);
RootPanel.get().add(grid);
RootPanel.get().add(grid);
}
但我得到以下異常：
onModuleLoad() threw an exception
Exception while loading module com.XXXX.client.TaskGWTEntryPoint. See Development Mode for details.
java.lang.reflect.InvocationTargetException

什麼模塊是必需的？這存在於我的* .gwt.xml中： <inherits name='com.extjs.gxt.ui.GXT'/>
爲什麼我的基本網格不起作用？ 感謝您的回答
