Geoff on GEF pt. II

So, carrying straight on from last night, I fixed the null pointer and now have an empty view displaying. The trouble is, as soon as I plugged in the listeners and updated the children of the EditPart when the model changed, I still get an empty view.

After some investigation I discovered that the following code can be used in a ViewPart to display a GEF diagram.

@Override
  public void createPartControl(Composite parent) {
    DefaultEditDomain defaultEditDomain = new DefaultEditDomain(null);
    
    sgv = new ScrollingGraphicalViewer();
    
    defaultEditDomain.addViewer(sgv);
    sgv.createControl(parent);
    ScalableRootEditPart sffrep = new ScalableRootEditPart();
    sgv.setRootEditPart(sffrep);
    sgv.setEditPartFactory(new TournamentEditPartFactory());
    
    sgv.getControl().setBackground(ColorConstants.listBackground);

    initView();
  }

  private void initView() {
    sgv.setContents(TournamentManager.get());
  }

However, my diagram is still not displaying as expected...
