Need help using DefaultModelBinder for nested model

Question

There are a couple of related questions, but I cannot find an answer that works.

Assuming I have the following models:

public class EditorViewModel
{
  public Account Account {get;set;}
  public string SomeSimpleStuff {get;set;}
}

public class Account
{
  public string AccountName {get;set;}
  public int MorePrimitivesFollow {get;set;}
}

and an extension ViewPage<EditorViewModel>view that does the following:

<%= Html.TextBoxFor(model => model.Account.AccountName)%>
<%= Html.ValidationMessageFor(model => model.Account.AccountName)%>
<%= Html.TextBoxFor(model => model.SomeSimpleStuff )%>
<%= Html.ValidationMessageFor(model => model.SomeSimpleStuff )%>

and my controller looks like this:

[HttpPost]
public virtual ActionResult Edit(EditorViewModel account)
{ /*...*/ }

How can I get DefaultModelBinder to properly bind my EditorViewModel? Without doing anything special, I get an empty instance of my EditorViewModel with all null or the default value.

The closest I came, UpdateModelmanually calling :

[HttpPost]
public virtual ActionResult Edit(EditorViewModel account)
{
    account.Account = new Account();
    UpdateModel(account.Account, "Account");
    // this kills me:
    UpdateModel(account);

, UpdateModel account ( ViewModel), " ... ". , , .

?
