title: Refactoring issue (Netbeans 8.1)
body: <p>Im using netbeans to develop some of my php projects. Everything worked fine until it received version 8.1 updates.</p>
  
  <p>Now, when i try to refactor a class method for example, it pops a message <code>"You can not refactor because this file is not part of an open project"</code>
  (I don't know if it says the exact same words in the english version because it's installed with my native lang pack)</p>
  
  <p>I just tried to exclude the entire project and did my checkout again (Im using subversion as version control for this project), but it keeps blocking me from refactoriong.</p>
  
  <p><strong>I am sure those files are part of an open project</strong> . Here's the screenshot:</p>

  <p>Any help would be very appreciated.</p>
  
  <p>~Edit:</p>
  
  <p>Example of refactoring:</p>
  
  <p>I have this public method inside my "Controller" class:</p>
  
  <pre><code>   /**
       * 
       * @return array
       */
      public function getAll(){
          return $this-&gt;_controllerData;
      }
  </code></pre>
  
  <p>Just trying to rename it to <strong>getData</strong> instead.
  (Right click the method name then go to <em>Refactor > Rename (Ctrl+R)</em></p>
