title: Line numbers in NSTextView (Lion compliant)
body: <p>I am trying to show line numbers in an NSTexView. I was using the solution from <a href="http://www.noodlesoft.com/blog/2008/10/05/displaying-line-numbers-with-nstextview/" rel="nofollow">http://www.noodlesoft.com/blog/2008/10/05/displaying-line-numbers-with-nstextview/</a> but it is no more working with Lion.</p>
  
  <p>Do you know an alternative solution?</p>
