未设置对象引用，没有源LInes，错误源是tmp文件

Question

当我尝试导航到我已部署到生产计算机的网站时，我收到以下错误。

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:


[No relevant source lines]

现在基本错误（对象引用未设置..）是我以前遇到过的。令我难过的是“没有相关的源代码行”以及错误的源文件是临时的。

我非常感谢有关问题的建议。

以下编辑

应加载的视图：

   @model Application_Portal.Models.Employee


<h2> New Employee Data Information</h2>


<form class="form-horizontal" method="post" id='newHireForm' action="NewEmpForm">

</form>

这是给我带来麻烦的控制器/视图组合：

    [Authorize]
    [NewHireFilter]
    public ActionResult NewEmpForm()
    {
        HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
        FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);
        Int32 newHireID = Convert.ToInt32(ticket.Name);
        Employee newEmp;

        newEmp = dbContext.Employees.FirstOrDefault(e => e.EmployeeID == newHireID);

        return View(newEmp);
                }

然而，这个工作正常：

       [Authorize]
    [NewHireFilter]
    public ActionResult ModuleOne()
    {
        ModuleOneViewModel vm = new ModuleOneViewModel();
        HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
        FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);
        Int32 newHireID = Convert.ToInt32(ticket.Name);

        vm.newHire = dbContext.Employees.FirstOrDefault(e => e.EmployeeID == newHireID);

        return View(vm);
    }

同样，我真的很感激任何帮助，因为这对我来说是一个令人困惑的问题。

感谢。
