TFS2012 - 无法使用某些模板创建新的团队项目

Question

我们刚刚设置了一个新的 TFS2012，但在使用 Scrum 2.2 和 CMMI 6.2（敏捷模板完美运行）时，不知何故创建新的团队项目停止工作。

TFS 抱怨试图将不可为 NULL 的列设置为 null：

在我看来，定义模板的 .xml 似乎已更改/损坏或其他什么。但我不知道从哪里开始，因为似乎没有其他人有类似的问题。

正如大多数答案所暗示的那样，我已尝试清除缓存，但没有运气。

我完全愿意接受建议:)

更新 SQL 服务器可以解决问题 (http://social.msdn.microsoft.com/Forums/en-US/c4266b7d-a221-473e-847b-ed6c04d8c03c/tf30162-task-wits-from-group-workitemtracking-failed)。究竟是什么问题，我不知道 - 但现在可以了。
