The binder should be able to bind to List property on a model

[jchannon]

If you have a model like so:

public class TestModel
{        
     public List<Friend> Friends { get; set; }
}

public class Friend
{
    public string Name { get; set; }
    public int Age { get; set; }
}

And you post data such as the below, the model binder will not assign the List property to the posted data

context.Request.Form["Friends[0].Name"] = "Steven";
context.Request.Form["Friends[0].Age"] = "21";
context.Request.Form["Friends[1].Name"] = "Andreas";
context.Request.Form["Friends[1].Age"] = "42";
