Object reference not set to an instance of an Object. Line 5: ViewBag.Title = Model.DisplayText;

Hi getting an error in post-build with the page title.

Details.cshtml ViewBag.Title = Model.DisplayText;

ComicBook.cs public string DisplayText { get { return SeriesTitle + " #" + IssueNumber; } }

I'd need to see more of the code to determine what's causing the error. Clearly, either "ViewBag" or "Model" is null at line 5, but the reason for it cannot be seen here.

Ellis,

As Steven mentioned, it's difficult to know what is the cause of the error without having more context. That being said, I would double check if the controller action method (that's associated with this view) is passing a data model object instance to the View method call.

Thanks ~James
