我正在使用 mojarra 2.2、gf4、swf 2.3.2。

问题出现在 webflow 中加载页面的过程中。当webflow（我认为）将页面发送到面部进行渲染时，错误就出现了。我已经尝试使用 swf2.0.8 到当前的 swf2.3.2。

我从某个地方借来的

每当我尝试打开页面时，我都会收到此错误

我在 Tomcat 6 上遇到了同样的问题。Spring WebFlow 的当前稳定版本没有正确实现 JSF 2.2 API。这就是调用javax.faces.context.ExternalContext.getClientWindow(...)失败的原因。问题的根源似乎是clientWindowId功能。

唯一的解决方案是将您的 Spring Webflow 库更新为 2.4 SNAPSHOT。我从http://maven.springframework.org/snapshot/org/springframework/webflow获取了库文件。我的 Spring Framework 是最新的稳定版本。

给 Tomcat 用户的注意事项。Spring Webflow 2.4 现在需要一些 Java EE 特性。您需要在项目中实现 CDI 规范。Weld 库非常适合在与 Java EE 不兼容的服务器上实现此规范（有关更多信息，请参见http://www.seamframework.org/Weld）。

这是 SWF 2.3.2 中的一个错误：它不支持 JSF 2.2

这是错误报告：https ://jira.spring.io/browse/SWF-1613

从 2.3.3 开始，它是固定的。
