Okay I've done that.

Now I've a problem. I've written the following code in my Action command 
for "Open"

      try
      {
         OverallModel model=new OverallModel(filename);
         MyEditorInput mei=new MyEditorInput();
         mei.setModelRoot(model);
         window.getActivePage().openEditor(mei, MyEditor.ID);
         System.out.println("Opened editor");
      }
      catch (Exception e)
      {
         e.printStackTrace();
      }


However I get error "Unable to create part" (no other information given).

I've gathered that the constructor of the MyEditor class is getting 
called and the init method is getting called but no other method is 
getting called. I figure the critical methods are the ones relating to 
the Graphical Viewer but those aren't getting touched.

Have no idea where to go from here. Any ideas?

Kevin.
