title: Netbeans does not show my code
body: <p>I have worked in project for long time but after electricity has cut off and my PC shutdown. </p>
  
  <p>The code in one of my frames not shown correctly, it's showing like this :</p>
  
  <p><img src="https://i.stack.imgur.com/I4Xt6.png" alt="no code!"></p>
  
  <p>I have GUI and its shape is fine. When I run the frame from main interface it works, but as I said the code is corrupted. I don't know why.  If any one has any solution for this problem it would be much appreciated.</p>
