我正在尝试在我的gwt应用程序中实现此示例：http://zenoconsulting.wikidot.com/blog:17但是当我尝试编译项目时出现此错误：

我在我的应用程序中添加了这个示例的类，我在我的gwt客户端类中创建了一个新的PsTable。
答案 0 :(得分：2)
GWT Incubator的最新版本仅与GWT 2.1兼容，您显然使用GWT 2.3或更高版本（2.3中添加Could not find an exact match rule. Using 'closest' rule…以支持IE9）。除此之外，GWT 2.2打破了生成器的二进制兼容性（它们必须针对GWT 2.2或更高版本进行重新编译），并且您有充分的理由发生故障。
在GWT Incubator主页上，您应该能够将PaagingScrollTable用途替换为GWT 2.4＆＃39; DataGrid。不可否认，这是一种截然不同的方法（细胞与小部件），但它是现在的发展方向：GWT孵化器已被弃用（有充分理由），你真的不应该使用它，离开如果您的项目使用它，并且绝对不开始在新项目中使用它。
