我非常确定我已经删除了一个函数名createGridView（），并且我还注释了pageLoad方法中的所有函数

我尝试清除并重新生成解决方案，但仍然保留相同的错误。 请帮忙。谢谢你的电话

对象引用未设置为对象的实例

告诉您程序中的一个变量是
null

线路

C:\Users\user\Desktop\30052012\LewreERP\u MixsolProject\Module\Sales.SalesOrder.salesOrderList.createGridView（）中的LewreERP\u MixsolProject.Module.Sales.SalesOrder.salesOrderList

告诉您源代码中哪一行有一个空值的变量

问题很可能不是您不再在localhost上运行，而是数据库中采用不同路径的代码或数据在此新服务器上不同

更新

在您的评论中，您说您已经删除了
createGridView（）
。但是，该功能显然是在服务器上运行的

这意味着您没有在服务器上运行最新的代码。

您好，我已经删除了createGridview函数。在我的后端代码中，我没有一个函数名CreateGridView。我发布了我的前端和后端编码。嗨，我没有发现错误。在我的服务器中，我没有C:\Users\user\Desktop\30052012\LewreERP\u MixsolProject\Module\Sales\SalesOrder\SalesOrderList中的任何文件。为什么我的项目将加载tis路径？这是编译时源代码所在的路径。相信我，如果您已经删除了createGridView，那么您的服务器上就没有正确的代码。在清除并重建之后-您是否将其部署到服务器上了？您好，我没有发现错误。在我的服务器中，我没有C:\Users\user\Desktop\30052012\LewreERP\u MixsolProject\Module\Sales\SalesOrder\Sa中的任何文件‌​lesOrderListing。为什么我的项目将加载它的路径？
