驗證約束importFrom拋出異常

當試圖從使用共享約束的域類導入約束時，我收到以下exepction。期間結合相發生異常驗證約束importFrom拋出異常

例外：

Property [somePackage.User.email] references shared constraint [email:null], which doesn't exist!

域：

class User { 
    String email 
    static constraints = { 
     email(shared: 'email', unique: true) 
}

命令

class UpdateClientCommand { 
    String email 

    static constraints = { 
     importFrom User 
    } 

}

堆棧跟蹤：

Property [clearhub.User.email] references shared constraint [email:null], which doesn't exist!. Stacktrace follows:

任何想法？

一些調試它似乎像這樣的情況後，不支持。我使用共享約束來支持'importFrom' – rgrebski

如果還有其他字段，您仍然可以使用importFrom並排除導致問題的特定字段。 – Vahid

如果你定義約束爲共享 - 它應該在grails.gorm.default.constraints 的的grails-app/conf目錄/ Config.groovy中定義。讓我猜猜，'電子郵件'沒有在那裏定義，所以你得到這個異常？

只需從用戶刪除「共享：」電子郵件「，」導入將正常工作。
