Buggy source:

  destinationPane=new DialogPane(getMessage(getRenderDialogDestinationLabelKey()));
  GroupLayout layout=new GroupLayout(destinationPane);
  destinationPane.setLayout(layout);
  JLabel destinationLabel=new JLabel(getMessage(getRenderDialogOutputFieldLabelKey()));
  JButton browseButton=new JButton(Icons.folder.getIcon());
  browseButton.setMargin(new Insets(0,0,0,0));
  browseButton.addActionListener(new ActionListener(){
    @Override public void actionPerformed(    ActionEvent e){
      if (!isBlank(destinationField.getText())) {
        fileChooser.setCurrentDirectory(new File(destinationField.getText()));
      }
 else {
        fileChooser.setCurrentDirectory(Settings.get().getLastUsedLocation());
      }
      fileChooser.showOpenDialog(RenderDialog.this);
      if (fileChooser.getSelectedFile() == null) {
        return;
      }
      destinationField.setText(fileChooser.getSelectedFile().getAbsolutePath());
    }
  }

  destinationField=new JTextField();
  destinationField.setToolTipText(getMessage(getRenderDialogOutputFieldTooltipKey()));
  destinationField.setMinimumSize(new Dimension(200,10));
  destinationField.addPropertyChangeListener("String_Node_Str",new PropertyChangeListener(){
    @Override public void propertyChange(    PropertyChangeEvent evt){
      updateOutputExampleLabel();
    }
  }

  destinationField.addFocusListener(new FocusAdapter(){
    @Override public void focusLost(    FocusEvent e){
