Question

我有一个NullReferenceException，但是当我试图保存Layout页面时。我正在使用电子邮件广告管理器。我已经构建了一个布局页面（ASPX），其中包含多个链接到自定义子布局（ASCX）的占位符

通过电子邮件管理器（“添加到此处”）添加这些Sublayout表单后，单击“保存”按钮并收到错误消息：

你知道原因是什么吗？如果没有，我该如何调试这类错误？

我认为这个问题与ECM模块中新注册的错误有关，我怀疑可能是因为时间段匹配而将原始票证放入其中。但是，如果不是您或者为了将此问题传递给可能遇到此问题的其他人，为了解决这个问题，您需要在Sitecore支持中加入票证。有一个初始修补程序，如果他们发现您的问题相同或相关，他们可以为您提供此修补程序。
