Question

我正在XPiNC中运行一个Xpages数据库，我希望将其用作＆＃34;前端＆＃34;到我们系统中的其他几个数据库。我将代码存储在此DB中并访问其他DB中的数据。

当我尝试在表单上执行简单的CRUD操作时，我收到一个我无法解释的错误。

我从中获取数据的数据库不在Xpages中，但我认为这不重要。

Answer 1

您的数据源定义databaseName="helpdesk.nsf" - 在XPiNC中它表示数据库的本地副本。你需要使用完整格式，如Paul所说：

databaseName="yourservername!!helpdesk.nsf"

我建议使用以下方法对服务器进行参数化：

databaseName="#{database.server}!!helpdesk.nsf"

我认为验证器因无效数据源的“无数据”而失败。

Answer 2

查看堆栈跟踪，它在Process Validations阶段失败 - 因此检查数据类型以进行验证/数据转换，并在DateTimeHelperRenderer上失败。它看起来像是指向computedField2。

有两种可能的解释：

其中一个视图条目在$ 1列中的值无法转换为日期。这听起来最有可能。
您遇到了我在博客上发布的部分刷新和行数据源不可用的问题http://www.intec.co.uk/dataviews-and-nested-repeats/。如果是这种情况，用if (view.isRenderingPhase()) {...}包装计算将解决问题。如果不是这种情况，它会将错误移至渲染响应阶段。
