Question

有没有人在页面加载表单页面时遇到此异常（例如联系我们）？我确实理解那里的值不应为null，但我不明白的是，错误跟踪是在加载页面后立即记录而不是提交操作。

其他信息：

版本：营销人员的Web表格8.0 rev.150224（更新-2） - 这与v.8.0-U3兼容所以应该没问题（我猜）
Sitecore实例的版本：8.0-U3

Answer 1

有一个特定于8.0更新3的WFFM版本。您应该首先尝试。请参阅wffm 8.0 update 3 page

如果没有，您可以尝试逐个删除字段，以查看它是特定字段还是字段类型。

您还可以尝试从正在运行的实例中删除wffm视图文件，并通过从zip安装或复制视图文件来重新部署它们。

Sitecore WFFM：ERROR值不能为null，参数名称：fieldId - 页面加载
