Caml 查询不适用于视图创建共享点

Question

我正在使用 C# CSOM 代码创建 Sharepoint 列表视图。我正在使用 ViewCreationInformation 来创建我的视图。我在为其编写查询时遇到问题。

写这篇作品：

            ViewCollection viewColl = list.Views;
            string[] viewFields = {"Id", "Action", "Created", "Created By"};
            ViewCreationInformation creationInfo = new ViewCreationInformation();
            creationInfo.Title = "FromCode";
            creationInfo.ViewFields = viewFields;
            creationInfo.Query = @"<Where><Neq><FieldRef Name=""ConfidentialDocument""/><Value Type=""Choice"">No</Value></Neq></Where><GroupBy><FieldRef Name=""TemplateName"" /><FieldRef Name=""Title"" /></GroupBy><OrderBy><FieldRef Name=""Created"" Ascending=""True"" /></OrderBy>";
            creationInfo.ViewTypeKind = ViewType.Html;
            creationInfo.RowLimit = 30;
            creationInfo.Paged = true;
            creationInfo.SetAsDefaultView = true;
            viewColl.Add(creationInfo);

但是如果我将查询更改为：

            creationInfo.Query = @"<Where><Neq><FieldRef Name=""ConfidentialDocument""/><Value Type=""Choice"">No</Value></Neq></Where><GroupBy Collapse=""TRUE"" GroupLimit=""30""><FieldRef Name=""TemplateName"" /><FieldRef Name=""Title"" /></GroupBy><OrderBy><FieldRef Name=""Created"" Ascending=""True"" /></OrderBy>";

然后View显示错误： TypeError: Unable to get property 'substring' of undefined or null reference

您可以查看 link 或者这里是错误：类型错误：无法获取未定义或空引用属性 'substring'

  TypeError: Unable to get property 'substring' of undefined or null referenceTypeError: Unable to get property '_events' of undefined or null reference

有人对此有任何想法吗？我搜索了很多地方，到处都发现类似的代码。我不知道为什么这段代码不起作用。

好的，问题出在 GroupLimit=""30""。没有 GroupLimit 的查询完全可以正常工作。

        creationInfo.Query = @"<Where><Neq><FieldRef Name=""ConfidentialDocument""/><Value Type=""Choice"">No</Value></Neq></Where><GroupBy Collapse=""TRUE""><FieldRef Name=""TemplateName"" /><FieldRef Name=""Title"" /></GroupBy><OrderBy><FieldRef Name=""Created"" Ascending=""True"" /></OrderBy>";
