title: Liferay 7 CE - Osgi module (liferay mvc portlet) not load javascript files
body: <p>I created a new liferay osgi module.
  My controller has the following tag :</p>
  
  <pre><code>@Component(
  immediate = true,
  property = {
      "com.liferay.portlet.display-category=Bla Modules",
      "com.liferay.portlet.instanceable=true",
      "javax.portlet.display-name=EventCalendar",
      "javax.portlet.init-param.template-path=/",
      "javax.portlet.expiration-cache=0",
      "com.liferay.portlet.footer-portlet-javascript=fullcalendar_year.js,/js/custom/main.js",
      "com.liferay.portlet.header-portlet-css=/css/fullcalendar_year.css,/css/fullcalendar.css",
      "javax.portlet.init-param.view-template=/view.jsp",
      "javax.portlet.resource-bundle=content.Language",
      "javax.portlet.security-role-ref=administrator,power-user,user"
  },
  service = Portlet.class
  </code></pre>
  
  <p>However the property </p>
  
  <blockquote>
    <p>com.liferay.portlet.footer-portlet-javascript</p>
  </blockquote>
  
  <p>is not loading all js files, it only loades the files if only one is called, if it is more than one nothing is loaded.</p>
  
  <p>Is this a bug or i am doing something wrong?</p>
