我創建從現有的實體CRUD，一切都很好，直到我去看到的結果，在這裏我得到了以下錯誤：的Symfony無法加載FieldVote
（使用的Symfony 3）
嘗試從命名空間 「的Symfony \分量\安全\的Acl \選民」 裝入類 「FieldVote」。 你忘記了另一個命名空間的「使用」語句嗎？ 500內部服務器錯誤 - ClassNotFoundException的
我不知道該怎麼辦這個問題，因爲沒有一個似乎永遠有這個問題，也沒有在那裏找到什麼原因造成的。
無論如何，這裏是從我的實體片段和我的控制器：

有ISN沒有提及代碼中的投票或任何內容，所以我不知道需要加載什麼FieldVote，或者什麼阻止它加載它。 有沒有人有想法？ 我必須準確，如果我去的任務/新，或任務/ {ID}或什麼的，它完美的罰款。
謝謝你提前
