Checkbox xpages-复选框为空

我在下面的问题上被指向了这个网站

我从OpenNTF.org借用了复选框代码。该计划是—

我已经将它集成到一个xPage中，在本地、web浏览器和手持设备上的notes客户端中运行时效果良好。但是，当在domino服务器上的复制副本上运行时，列数的值为null。domino服务器是8.5.3FP1

不确定为什么只有通过notes客户机在domino服务器上运行时才会出现错误，而在本地客户机上运行正常

谢谢， 沃尔特

这里是错误

意外的运行时错误 运行时遇到意外错误。 误差源 页面名称：/Company.xsp 控件Id:行重复

例外情况 执行JavaScript计算表达式时出错 脚本解释器错误，行=1，列=37:“compositeData.FieldValues”为 空的

JavaScript代码

Math.ceil(compositeData.FieldValues.length / compositeData.numberOfColumns);

脚本解释器错误为“'compositeData.FieldValues'为空”。与任何自定义控件的上下文一样，

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

，则无论将哪个表达式分配给自定义控件的

FieldValues

属性，该表达式的计算结果都为

null

在您的例子中，表达式

compositeData.FieldValues.length

抛出一个错误，因为

null

没有长度（…或任何其他属性或方法）

您已经指出，在以下情况下，这可以正常工作：

• Notes客户端，本地副本
• 浏览器访问服务器
• 移动设备访问服务器

这三种场景的共同点是代码在本地计算机上运行。当您通过浏览器（包括移动设备）访问XPage时，您正在访问某个服务器，但执行的代码本身是本地的。。。它不必调用另一个Domino服务器来运行代码

---

因此，它失败的一个场景是不正确的一个场景：从Notes客户端访问服务器副本。我猜传递给

FieldValues

的表达式使用的是

@DbLookup（）

或类似的操作，但没有正确说明代码在哪个服务器上运行，导致它将

null

传递给自定义控件。

您应该在OpenNTF上的组件讨论中写下这篇文章。因为这可能是一个应用程序问题。该组件的开发人员将是最好的回答。您对ACL和服务器副本上的相同数据拥有足够的权限吗？我已向项目开发人员发送电子邮件，他们建议我将其发布在此处。那里的ACL很好，因为我通过浏览器和notes客户端使用相同的ID访问它。如果是和ID问题，浏览器或手持设备应显示相同的结果。它适用于服务器上的手持设备，而不适用于同一服务器副本上的PC浏览器？我仍然会再戳开发人员一些。）复合数据对象未初始化。这是您创建的还是组件。另一个选项是将其简化为示例，并将源粘贴到问题中。它确实执行查找，我将检查dblookup公式。在查找中，它没有查看服务器。我在找一个本地数据库。谢谢你的帮助
