ASP.NET MVC Model Binder returns null object

Question

I am having a problem where everytime I post a form back to the [HttpPost] version of my controller action, the ModelBinder returns a null object. I can\'t work

Answer 1

The problem is that there is a name collision between the property named Model in the class DeviceModel and the variable named model in the Create action. The name collision causes the DefaultModelBinder to fail, since it tries to bind the Model property to the DeviceModel class.

Change the name of the variable in the Create action to deviceModel and it will bind correctly.
