Buggy source:
@Override public void update(ModelEvent event){
  if (event.part == ModelPart.MODEL) {
    this.model=(Model)event.data;
  }
 else   if (event.part == ModelPart.CRITERION_DEFINITION) {
    if (model != null) {
      root.setRedraw(false);
      table.removeAll();

Fixed version (ground truth):

    this.model=(Model)event.data;
  }
  if (event.part == ModelPart.CRITERION_DEFINITION || event.part == ModelPart.MODEL) {
    if (model != null) {
      root.setRedraw(false);
      table.removeAll();
      if (model.getKAnonymityModel().isActive() && model.getKAnonymityModel().isEnabled()) {
        TableItem item=new TableItem(table,SWT.NONE);
        item.setText(new String[]{"String_Node_Str",model.getKAnonymityModel().toString(),"String_Node_Str"});
        item.setImage(0,symbolK);
      }
      if (model.getDPresenceModel().isActive() && model.getDPresenceModel().isEnabled()) {
        TableItem item=new TableItem(table,SWT.NONE);
        item.setText(new String[]{"String_Node_Str",model.getDPresenceModel().toString(),"String_Node_Str"});
        item.setImage(0,symbolD);
      }
      for (      ModelLDiversityCriterion c : model.getLDiversityModel().values()) {
        if (c.isActive() && c.isEnabled()) {
          TableItem item=new TableItem(table,SWT.NONE);
          item.setText(new String[]{"String_Node_Str",c.toString(),c.getAttribute()});

        }
      }
