Fixed version (ground truth):

  Label menuParentIDLabel=toolkit.createLabel(composite,"String_Node_Str",SWT.NULL);
  menuParentIDLabel.setLayoutData(new GridData(SWT.BEGINNING,SWT.CENTER,false,true,1,1));
  menuParentIDCombo=new Combo(composite,SWT.READ_ONLY | SWT.DROP_DOWN | SWT.SINGLE);
  GridData gridData=new GridData(SWT.BEGINNING,SWT.FILL,true,true,1,1);
  gridData.widthHint=150;
  menuParentIDCombo.setLayoutData(gridData);
  menuParentIDCombo.addSelectionListener(new SelectionListener(){
    public void widgetDefaultSelected(    SelectionEvent e){
    }
    public void widgetSelected(    SelectionEvent e){
      if (menuParametersRefreshing)       return;
      menuPositionCombo.select(0);
      commitMenuParameters();
