title: Struts Assistant Tool Window does not come up in IntelliJ
body: <p>I have a project with the Struts 2 framework detected successfully in IntelliJ <em>(12.1.6).</em></p>
  <p>However, I am not able to see the Struts Assistant Tool Window. I am looking for that and Tiles support inside IntelliJ.  The web application compiles and deploys fine but I constantly get these inspection warnings inside the IDE.</p>
  <p>I am also unable to add more files to the feature set manually. Is there something extra to be done for the Struts assistant tool window to appear?</p>
  <p>Also, There is no Struts Assistant Tool Window in <code>View|Tool Window</code> Menu.
  Note: Have tried Invalidate Cache already.</p>
