ASP.NET MVC model validation error with edit scenario

Question

I am following Scott Gu's tutorial on ASP.NET MVC 2 model validation: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx I am using Linq To SQL so tried the buddy class technique. This works fine when using a Create scenerio as in Scott's tutorial. But when used with an edit scenerio I am getting an error InvalidOperationException, the model of type .. could not be updated.

Danny... We would have to see more of your code to be able to help, with the information you are providing it is not possible to tell if this is a L2S issue or an MVC2 issue. — Roberto Hernandez

The error was returned as I did not reset the ViewData when a validation error occurs.
