title: It is possible to combine ValidationSummary(true) and ModelState.AddError("field", "error")?
body: <ul>
  <li><p>I use ValidationSummary(true) to print model validation errors in<br>
  one place and property validation errors near each field.</p></li>
  <li><p>In the controller i add a property error : ModelState.AddError("property","error")</p>
  
  <p>I see the message validation error for that property but i also got the validation-summary-errors div although i have no model error. 
  What am i doing wrong and why is that div generated if i have no model errors?</p>
  
  <pre><code>&lt;div class="validation-summary-errors"&gt;
      &lt;ul&gt;
            &lt;li style="display:none"&gt;&lt;/li&gt;
      &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre></li>
  </ul>
