为什么保存在第二次使用时发送错误

我有一个包含计算定价的库的订单。 document1是主要的客户数据源，docLineItem是有序数据源的项目。当用户输入要添加到订单的项目时，代码会创建项目记录并使用订单的总计更新主文档1记录（小计，扩展总计...）。如果我输入订单并输入客户并输入第一个项目，则会正确保存。当我输入第二个项目时，代码会在document1保存上抛出一个错误（调用方法NotesXspDocument.save（）null的异常）。为什么要这样做？

    docLineItem.replaceItemValue("ItemPrice", Number(vQtyPrice));
    docLineItem.replaceItemValue("ItemExtPrice", Number(vExtPrice));
    docLineItem.replaceItemValue("IncenInd", viewScope.vsIncenInd);
    docLineItem.replaceItemValue("SplitInd", viewScope.vsSplitInd);
    docLineItem.save(true);

    document1.replaceItemValue("OrderSubTot", Math.round((vSubTot * 100) / 100));
    document1.replaceItemValue("OrderIncenTot", Math.round((vIncenTot * 100) / 100));
    document1.replaceItemValue("OrderTDTot", Math.round((vTDTot * 100) / 100));
    document1.replaceItemValue("OrderGTot", Math.round((vGTot * 100) / 100));
    document1.save();

非常有趣。 根据{{​​3}}，你有可能用null Vector填充一些项目。确认this post。

答案 1 :(得分：0)

我经常发现对XSPDocument“后面”的文档的更改会导致任何使用它作为句柄抛出null。它就好像变量不再与其后面的文档有连接。在我的一些测试中，它将返回背景文档的NotesID或UNID，但XSPDocument仍然会出现null错误。

当我遇到这样的情况时，我将NoteID或UNID存储在变量中并创建一个要保存的新实例。

我不确定这是最有效的方法（事实上，我确定它不是），但它一直有效，直到我可以确定为什么XSPDocument似乎丢失了它的连接（我还没有发现） 。我很想看到更好的方法。
