我使用在群集WebLogic Server上运行的Primefaces 6.1（Mojarra 2.2.8）版本：12.2.1.3.0并且在会话复制期间我得到以下异常：

JSF组件绑定从未在应用程序中使用。查看Primefaces源代码，我可以看到模型SortMeta（不实现Serializable）仅用于DataTable组件。
视图状态保存方法必须是服务器端。
如何解决或避免此异常？
修改
问题是由＆＃34; new＆＃34; datatable属性multiViewState。

Class SortMeta现在可以序列化： https://github.com/primefaces/primefaces/issues/3272
