我已閱讀關於此錯誤的每個線程，我無法揣摩出這是來自。陣列字符串轉換ArrayChoiceList
我有很多正在從陣列填充複選框字段的形式。然而，在我的實體，我將所有的字段轉換爲一個逗號分隔的字符串（是的，我知道這是醜陋的）和問題的領域都工作正常，但我得到這個錯誤，我根本無法弄清楚問題在哪裏來自。當我調試這些領域它給了我，是正在討論的陣列和我能夠解決這些問題
我也有另外4組的EntityType選擇列表，從4個其他數據庫表填充的。所有的數據和拉正常工作的所有實體，但是當我試圖堅持，我得到這個錯誤的數據庫是，但我找不到什麼實體或陣列/場，這是指任何引用。我在下面看到的是空陣列。
如果看到我的實體和FormType幫助，我可以張貼的。

ProgramsType表格類 這有m y實體添加，但也提到有大量其他ChoiceType字段從數組中填充，但這些似乎都工作正常。
