This time, including a SaveCapability for the Node:

public class ShipNode extends BeanNode implements PropertyChangeListener { private final InstanceContent ic; private final ShipSaveCapability saveCookie; public ShipNode(Ship bean) throws IntrospectionException { this(bean, new InstanceContent()); } public ShipNode(Ship bean, InstanceContent ic) throws IntrospectionException { super(bean, Children.LEAF, new ProxyLookup(new AbstractLookup(ic),
      Lookups.singleton(bean))); this.ic = ic; setDisplayName(bean.getType()); setShortDescription(String.valueOf(bean.getYear())); saveCookie = new ShipSaveCapability(bean); bean.addPropertyChangeListener(WeakListeners.propertyChange(this, bean)); } @Override public Action[] getActions(boolean context) { List<? extends Action> shipActions = Utilities.actionsForPath("Actions/Ship"); return shipActions.toArray(new Action[shipActions.size()]); } protected void fire(boolean modified) { if (modified)
      { ic.add(saveCookie); } else { ic.remove(saveCookie); } } private class ShipSaveCapability implements SaveCookie { private final Ship bean; public ShipSaveCapability(Ship bean) { this.bean = bean; } @Override public void save() throws IOException { StatusDisplayer.getDefault().setStatusText("Saving..."); fire(false); } } @Override public boolean canRename() { return true; } @Override public void setName(String s) { Ship c = getLookup().lookup(Ship.class); String oldDisplayName = c.getType();
