Question

我已经在6.7.2上开发了相当长的一段时间，昨天我注意到我的应用程序看起来很奇怪。我去了调试版，发现了这个：

Starting Vaadin client side engine. Widgetset: Xinco
Widget set is built on version: 6.7.2
Warning: widgetset version 6.7.2 does not seem to match theme version
Starting application xincovaadin-1652339780
Vaadin application servlet version: 6.7.2
Application version: NONVERSIONED
inserting load indicator
Making UIDL Request with params: init
Server visit took 30ms
JSON parsing took 0ms
Assuming CSS loading is not complete, postponing render phase. (.v-loading-indicator height == 0)

我该如何解决这个问题？我试着没有运气重建我的小部件。上面第11行重复了很多次。

源代码可以从here下载。该项目是一个NetBeans项目。

Answer 1

您使用的是哪个主题？假设它是一个自定义主题，如果您使用默认主题，错误消息是否会消失？

同时确保：

您已清理项目和应用程序服务器，并重建了项目
您的WEB-INF / lib目录中没有两个不同版本的Vaadin JAR
您尚未将旧版Vaadin JAR中的主题目录复制到您的VAADIN / themes目录
您的（假设的）自定义主题不会继承任何旧主题
如果您在浏览器中检查加载的css文件（当我尝试使用时，Firebug就派上用场了），styles.css（或其中一个styles.css'）包含以下开头部分：

.v-theme-version：after { 内容：“6_7_2”; } .v-theme-version-6_7_2 { display：none; }

我设法产生此错误的唯一方法是从另一个Vaadin版本的主题继承自定义主题。

更新：我检查了你的项目，我想我知道什么是错的。 web.xml中的servlet映射应该是/ VAADIN / *而不是/ vaadin / *。如果将主题从vaadin.jar复制到项目中的VAADIN / themes，它应该可以在没有此更改的情况下工作。通常，您还应该复制Vaadin小部件集，但由于您使用的是自定义小部件集，因此您不必执行此操作。

Answer 2

您是否从VAADIN/themes中提取了vaadin.jar文件夹，以便静态提供？在这种情况下，您需要使用Vaadin 6.7.2中的内容更新该目录。

或者，您是否在VAADIN / themes下创建了一个与您正在使用的Vaadin主题同名的文件夹？

Vaadin警告：widgetset版本6.7.2似乎与主题版本不匹配
