我正在尝试将项目从JSF 1.2升级到2.2.18。该应用程序运行良好，可以访问页面，但是主要问题是当我尝试使用按钮玩游戏时，出现以下异常。我已经搜索了这个问题并尝试了一些解决方案，但是除了将javax.faces.PARTIAL_STATE_SAVING设置为false之外，其他解决方案均无效。但是在这种情况下，页面的行为会发生变化，f.i文本框会显示在页面底部。另一方面，我什至不确定该参数是否应该设置为false。一些依赖项是：

我非常担心Tomahawk21会导致此问题，并且不知道如何解决。 <t:saveState value="#{refererBean.referer}"/>使用了这种saveState标记。
