Well how about this:

I exposed the protected UpdateModel in my controller:

public void UpdateModel(BusinessSavingsRequest bsr, string[] keys)
{
base.UpdateModel(bsr, keys);
}

and then call it from my binder:

public object GetValue(ControllerContext controllerContext, string modelName, Type modelType, ModelStateDictionary modelState)
{
BusinessSavingsRequest bsr = new BusinessSavingsRequest();
string[] properties = typeof(BusinessSavingsRequest).GetProperties().Select(p => p.Name).ToArray();
((MvcApplication.Controllers.BusinessSavingsController)controllerContext.Controller).UpdateModel(bsr, properties);
return bsr;
}

Perhaps if this is all it needed to do I wouldnt have a custom binder for the type.

The ComplexModelBinder doesn't make much sense in his post.

How do you use it? Why the need to 'register' it.

Seems to me if you pass a complex type as a parameter, it would map the form variables to the type with reflection - and only if you need to have more complex mapping would you create a specific binder...

Yeah, I love Disqus... I actually don't have to log in to my admin tool to
moderate my comments. I simply reply to a comment with "approve" and it
gets approved. Or If I reply with some other text, it approves the comment
and submits my text as a comment. Very neat.
I am looking into the ComplexModelBinder and trying to get things working
with the built-in stuff :)

You are absolutely right. It is hard to find these things without good
documentation. But I just found some info at
http://weblogs.asp.net/scot...
I will update the post to direct readers there.

Thanks for the heads up.

Isn't this what the ComplexBinder that comes with MVC P5 already does?
