Question

I am using two actions one for the get portion of my request (a generic looking url) and another for the post.

In the case that a post has ModelState errors, I would like to view to return to show the errors but I would like the url to be the generic url.

So this is what currently happens:

Get: http://foo.com/mycontroller  
Post: http://foo.com/mycontroller/specificviewaction (validation error occurs)  
Resultant url is: http://foo.com/mycontroller/specificviewaction

Where as I want it to be http://foo.com/mycontroller the appropriate errors.

Here is my current code:

    public ActionResult Index()
    {
        // ... do stuff
        return View("specificviewaction ", model);
    }

    [HttpPost] 
    public ActionResult specificviewaction(Model model)
    {
        if (ModelState.IsValid)
        {
        // ... do stuff
        }

        return View("specificviewaction", model);
    }

Note, there is no actual Index view, only specific views.

This is what I ended up doing.

I left the routing table as per the default implementation.

Then for each model type, I am putting a hidden field in the form with which type it is.

On the post, I check what type it is and use TryUpdateModel to update an instance of the model with the correct form values.

If it succeeds great, if not I can deliver the appropriate errors back.

I was trying to over think it, simplest approach was best.
