I have a controller with two simple Methods:

UserController Methods:

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Details(string id)
{
 User user = UserRepo.UserByID(id);

 return View(user);
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(User user)
{
 return View(user);
}

Then there is one simple view for displaying the details:

<% using (Html.BeginForm("Details", "User", FormMethod.Post))
   {%>
 <fieldset>
  <legend>Userinfo</legend>
  <%= Html.EditorFor(m => m.Name, "LabelTextBoxValidation")%>
  <%= Html.EditorFor(m => m.Email, "LabelTextBoxValidation")%>
  <%= Html.EditorFor(m => m.Telephone, "LabelTextBoxValidation")%>
 </fieldset>
 <input type="submit" id="btnChange" value="Change" />
<% } %>

As you can see, I use an editor template "LabelTextBoxValidation":

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<string>" %>
<%= Html.Label("") %>
<%= Html.TextBox(Model,Model)%>
<%= Html.ValidationMessage("")%>

Showing user information is no problem. The view renders perfectly user details. When I submit the form, the object user is lost. I debugged on the row "return View(User);" in the Post Details method, the user object is filled with nullable values. If I dont use the editor template, the user object is filled with correct data. So there has to be something wrong with the editor template, but can't figure out what it is. Suggestions?
