嘗試爲INRegister設置擴展字段值時出現「更新」錯誤

Question

我嘗試在創建並向KitAssemblyEntry圖形中插入新的INKitRegister對象後，爲INRegister設置擴展字段值。我瞭解INKitRegister在保存時有一種方法可以創建存儲在數據庫數據庫中的INRegister。保存後，我有要執行的代碼，將設置我添加到INRegister數據表中的擴展字段。執行此代碼時，出現以下錯誤：

Error #78: Another process has updated the 'INRegister' record. Your changes will be lost.

我不確定爲什麼，因爲我在數據表條目完成後執行此編輯。

這裏是我的代碼：

 ...//Code to create component children 

     INKitRegister kitHeader = new INKitRegister 
     { 
      //set header fields 
     }; 

     //I also have this extended field on the INKitRegister DAC 
     INKitRegisterExt kitHeaderExt = PXCache<INKitRegister>.GetExtension<INKitRegisterExt>(kitHeader); 
     kitHeaderExt.UsrWOID = CurrentDocument.Current.Id; 

     INTranSplit kitParentAssembly = new INTranSplit 
     { 
      //Making INTranSplit entry for kit 
     }; 

     ... 
     //Do I need to get the graph's extension? set register view? do I need to get kitHeader's inserted refNbr and forward that to function to set woid? 
     KitAssemblyEntry graphKAE = PXGraph.CreateInstance<KitAssemblyEntry>(); 
     graphKAE.Document.Insert(kitHeader); 
     graphKAE.Document.Current.KitRevisionID = "1"; 
     graphKAE.Actions.PressSave(); 

     foreach (INComponentTran ch in kitChildren) 
     { 
      ch.RefNbr = kitHeader.RefNbr; 
      graphKAE.Components.Insert(ch); 
     } 

     graphKAE.Actions.PressSave(); 

     //Code in which I get the newly created INRegister and set the extended field. 
     string refNbr = graphKAE.Document.Current.RefNbr; 
     INRegister reg = PXSelect<INRegister, Where<INRegister.refNbr, Equal<Required<INRegister.refNbr>>, And<INRegister.docType, Equal<Required<INRegister.docType>>>>> 
      .Select(this, refNbr, "P"); 
     INRegisterExt regExt = PXCache<INRegister>.GetExtension<INRegisterExt>(reg); 
     regExt.UsrWOID = CurrentDocument.Current.Id; 

     INRegisters.Update(reg);   

     this.Actions.PressSave(); 


     PXRedirectHelper.TryRedirect(graphKAE, PXRedirectHelper.WindowMode.Popup); 

有什麼建議？我試着將代碼放在INAcitRegister_RowPersisting和INKitRegister_RowUpdating下的KitAssemblyEntry_Extension類中。我還研究了在彈出窗口關閉時可能執行的更新，但我不知道該怎麼做。歡迎任何幫助，讓我指出正確的方向。

這表明您擁有的記錄不是最新的，因爲它存在於數據庫中。嘗試使用PXSelectReadonly代替PXSelect以獲取您的INRegister（reg）對象。

我認爲這是行「INRegisters.Update（reg）;」那麼保存是失敗的？

我也會嘗試使用套件圖更新INRegister並選擇註冊表。嘗試更改這一部分...

//Code in which I get the newly created INRegister and set the extended field. 
string refNbr = graphKAE.Document.Current.RefNbr; 
INRegister reg = PXSelectReadOnly<INRegister, 
    Where<INRegister.refNbr, Equal<Required<INRegister.refNbr>>, 
    And<INRegister.docType, Equal<Required<INRegister.docType>>>>> 
    .Select(graphKAE, refNbr, "P"); 
INRegisterExt regExt = PXCache<INRegister>.GetExtension<INRegisterExt>(reg); 
regExt.UsrWOID = CurrentDocument.Current.Id; 

graphKAE.Caches[typeof(INRegister)].PersistUpdated(graphKAE.Caches[typeof(INRegister)].Update(reg));
