我在下面的问题中被指向这个网站。

我借用了OpenNTF.org的checkbox代码。该项目是- http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&documentId=CDD107F4006F7D5C8625775F001B8C61

我已经将它集成到一个xPage中，当在本地的notes客户端、web浏览器和手持设备上运行时，它工作得很好。但是，当在domino服务器上的副本上运行时，列数的值进入is null。domino服务器是8.5.3 FP1。

不确定为什么只有在domino服务器上通过notes客户端才会出现错误，而它在客户端本地工作得很好。

谢谢，沃尔特

脚本解释器错误为"'compositeData.FieldValues‘is null“。在任何自定义控件的上下文中都是如此，compositeData是引用传递到自定义控件的属性映射的变量。因此，如果compositeData.FieldValues为null，则无论为自定义控件的FieldValues属性分配什么表达式，该表达式的计算结果都是null。

在本例中，表达式compositeData.FieldValues.length抛出错误，因为null没有长度(...or任何其他属性或方法)。

您已经指出，这在以下场景中工作得很好：

本地replica

  • Browser访问server

  • Mobile设备访问服务器
  • Notes客户端

这三个场景的共同点是代码都在本地运行。当你通过浏览器(包括移动设备)访问XPage时，你是在访问一些服务器，但是执行的代码是本地的……它不必对另一个Domino服务器进行NRPC调用即可运行代码。

因此，它失败的一个场景是一个不正确的场景:从Notes客户机访问服务器副本。我猜您传递给FieldValues的表达式正在使用@DbLookup()或类似的操作，但是没有正确地考虑到代码在哪个服务器上运行，从而导致它将null传递给自定义控件。
