MVC2 Controller is passed a null object as a parameter
- by Steve Wright
I am having an issue with a controller getting a null object as a parameter:
[HttpGet]
public ActionResult Login()
{
return View();
}
[HttpPost]
public ActionResult Login(LoginViewData userLogin)
{
Assert.IsNotNull(userLogin); // FAILS
if (ModelState.IsValid)
{
}
return View(userLogin);
}
The LoginViewData is being passed as null when the HttpPost is called: Using MvcContrib.FluentHtml:
<h2>Login to your Account</h2>
<div id="contact" class="rounded-10">
<%using (Html.BeginForm()) { %>
<fieldset>
<ol>
<li>
<%= this.TextBox(f=>f.UserLogin).Label("Name: ", "name") %>
<%= Html.ValidationMessageFor(m => m.UserLogin) %>
</li>
<li>
<%= this.Password(u => u.UserPassword).Label("Password:", "name") %>
<%= Html.ValidationMessageFor(m => m.UserPassword) %>
</li>
<li>
<%= this.CheckBox(f => f.RememberMe).LabelAfter("Remember Me")%>
</li>
<li>
<label for="submit" class="name"> </label>
<%= this.SubmitButton("Login")%>
</li>
</ol>
</fieldset>
<% } %>
<p>If you forgot your user name or password, please use the Password Retrieval Form.</p>
</div>
The view inherits from MvcContrib.FluentHtml.ModelViewPage and is strongly typed against the LoginViewData object:
public class LoginViewData
{
[Required]
[DisplayName("User Login")]
public string UserLogin { get; set; }
[Required]
[DisplayName("Password")]
public string UserPassword { get; set; }
[DisplayName("Remember Me?")]
public bool RememberMe { get; set; }
}
Any ideas on why this would be happening?
UPDATE
I rebuilt the web project from scratch and that fixed it. I am still concerned why it happened.
