Jsf Primefaces 10 dataTable p:dataExporter在迁移后渲染时生成ArrayIndexOutOfBoundsException

环境：

• JBoss7.2
• 素数面10
• 爪哇11

我已经从primefaces 8迁移到primefaces 10 dataTable p:dataExporter在呈现xhtml时生成ArrayIndexOutOfBoundsException。 当我注释掉dataexporter时，xhtml呈现良好

接下来唯一重要的变化似乎是taht PDF库已从iText切换到Libre OpenPDF

我尝试了两种不同的语境，一种有效，一种无效，不同之处：

• 它工作的上下文没有身份验证
• 它不工作的上下文具有KeyClock身份验证和两个主题依赖项

我认为这与primefaces主题无关，但可能是因为KeyClope在日志错误中显示了处理请求

为什么要给出这个错误

服务器错误

我终于找到了无法使用p:dataExporter导出文件的问题

xml文件包含上下文参数javax.faces.PARTIAL_STATE_SAVING被定义为false，所以我注释掉了，我工作得很好

web.xml中的问题
