title: FluentValidation summary always displaying
body: <p>I'm using FluentValidation form a form, and the Validation summary seems to be displayed at load time. I don't have anything that seems to submit the form automatically and in my controller, no validation check is made until the form is posted. Weird enough, validation seems to work perfectly when submiting.</p>
  
  <p>ViewModel:</p>
  
  <pre><code>[Validator(typeof(SendMessageInputValidator))]
  public class SendMessageInput
  {
      public string Title { get; set; }
      public string Content { get; set; }
      public string VideoUrl { get; set; }
      public string CultureName { get; set; }
      public bool VideoMode { get; set; }
  }
  
  public class SendMessageInputValidator : AbstractValidator&lt;SendMessageInput&gt;
  {
      public SendMessageInputValidator()
      {
          RuleFor(s =&gt; s.Title)
              .NotEmpty().WithMessage("TitleRequired".Translate("MCN"));
      }
  }
  </code></pre>
  
  <p>Controller:</p>
