Jfreechart extension 2 and Jfreechart 1.0.0

Hi 
  
  I am having problems  using Jfreechart extension 2 along with Jfreechart 1.0.0 library.  
  
  The problem comes when the addChartEventListener  listener gets fired 
  
  
  fChartComponent = new ULCJFreeChartComponent();
  ...........  
  ............
  fChartComponent.addChartEventListener(new ChartHandler());
  
  
  I get the following error when mouse listener  gets fired 
  
  Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException

  I  guess in its not able to find UIChartEntity based on x and y  co-ordinates 
  
  I understand that jfreechart extension 2  i should be using  Jfreechart 0.9.0
  but it could be 
 good if both jfreechart extension 1 and 2  use the same library. 
  
  
 
 Thanks, 
  Gene
