title: Portlet doesn't process action phase
body: <p>I have a portlet basically simple form. When i enter on that page with form directly for the first time and submit it, my page is only reloaded. On second submit it works.</p>
  
  <p>Next case is, when i enter on that page from another page by link. It works on first time.</p>
  
  <p><strong>We using:</strong></p>
  
  <ul>
  <li>java 8</li>
  <li>Liferay 6</li>
  <li>spring-webflow 2.4.4</li>
  <li>spring 4.3.12</li>
  </ul>
