Question

我有一个使用JSF 2.0.11和RichFaces 4.3.4的应用程序。我尝试升级到JSF 2.1.19并开始获得以下异常。它似乎没有意义，因为应用程序构建良好

此异常表明运行时类路径包含JSF 1.x API以及JSF 2.x impl。该方法在JSF 2.0 API中确实是introduced，并且在任何JSF 1.x API中都不存在。

清理运行时类路径以摆脱那些JSF 1.x API库。通常，它们具有文件名jsf-api.jar。如有必要，请将JSF 2.1.19兼容的API放在适当的位置。如果您使用单个javax.faces-2.1.19.jar文件，则不应该这样做。

如果徒劳无功，请详细说明您正在使用哪个servletcontainer impl / version以及哪些文件都存在于构建的WAR文件的/WEB-INF/lib文件夹中。

升级到JSF 2.1.19后，类型UIViewRoot的方法getViewMap（）未定义
