title: java - slick2d - statebasedgame error - No OpenGL context found in the current thread
body: <p>I've just started playing with slick2d's state based game structure. I've set up the main class as follows</p>
  
  <pre><code>    public static final int newMenu = 0;
  
      /**
       * @param args the command line arguments
       */
      public static void main(String[] args) {
          AppGameContainer appgc;
          try {
              appgc = new AppGameContainer(new StateBased("StateBased Test"));
              appgc.setDisplayMode(640, 360, false);
              appgc.start();
          } catch (SlickException e) {
          }
      }
  
      public StateBased(String name) throws SlickException {
          super(name);
          this.addState(new NewMenu(newMenu));
      }
  
      @Override
      public void initStatesList(GameContainer gc) throws SlickException {
          this.getState(newMenu).init(gc, this);
      }
  </code></pre>
  
  <p>now the new menu class so far has</p>
  
  <pre><code>    private final int state;
      private final Image bg;
      private final static String directory = "Images/StartScreen/";
  
      public NewMenu(int state) throws SlickException {
          this.state = state;
          bg = new Image(directory + "loadbg.png");
      }
  </code></pre>
  
  <p>but i'm getting at error at the "bg=new image" line. "No OpenGL context found in the current thread." I'm confused since I haven't got this when using basicgame instead of statebasedgame</p>
  
  <p>Can anyone help me solve this</p>
  
  <p>This is the full error</p>
