xPage managedBean ODA应用程序错误

时间：2016-06-01 07:38:26

标签： java xpages

从一个页面导航到另一个页面时不断出现以下错误。 错误与我的任何代码无关，至少来自堆栈跟踪。 从调试打印看起来它是在页面加载后发生的。

有什么想法吗？

答案 0 :(得分：1)

您不能将任何Domino对象存储在托管bean中。正如该方法所说，它不可序列化。官方发展援助无法解决这个问题。

我的建议是存储DominoDocument对象（如果你需要前端文档，所以在bean的生命周期内更新它但不保存每次）或UNID（如果你只需要后端文档） 。 Database.getDocumentByUNID()非常快，因此您不应该担心获取文档对性能的影响。

如果要避免在XPage生命周期中多次获取文档，请将生成的Document对象放在requestScope中，并在从数据库检索之前检查它。或者（我不确定如何最好地实践它或者如果它被正确清理）可以选择将变量设置为transient，因此它不会在每个请求结束时被序列化，但是将在每次部分刷新期间在bean中保存。
