I had the same issue. The answer is instead of overriding BindModel() in your custom model binder, override CreateModel()...
After inspecting the source for System.Web.MVC. DefaultModelBinder, it looks like this can be solved using a slightly different approach. If we rely more heavily on the base implementation of BindModel, it looks like we can construct a PhotoImpl object while still pulling the validation attributes from IPhoto.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
