How to notify GUI elements of data model changes - Listeners?


I spent the last couple of hours thinking about the following problem:
I have a DataModel (basically Java classes with some Lists) and several Vaadin tables that displays the data. The data is modified by different Vaadin elements. Here comes my problem:
How to update all depending Vaadin tables after some data is modified?

Here’s a basic example code:

public class Demo extends VerticalLayout {

    private DataStructure data = new DataStructure("John", "Maria", "Steve");
    private Table table = new Table("Names");

    public Demo() {
        NativeButton addButton = new NativeButton("Add Name");
        addButton.addListener(new Button.ClickListener() {

            public void buttonClick(ClickEvent event) {

    public void refreshTable() {
        IndexedContainer container = new IndexedContainer();
        Item item = null;
        container.addContainerProperty("Name", String.class, null);
        for (String name : data) {
            item = container.getItem(container.addItem());

As you can see I have to manually call refreshTable(); In a more complex scenario I would have to call refreshTable() for all of my different tables.

The question is: How to design a better and more generic solution for this problem?
May it is possible to work with Listeners?

If you have Beans/POJOs that you wish to add to a table, the standard way is to use the BeanItemContainer.

Then, if you have an editor to edit the beans, the BeanItem communicates the changes in the bean properties to the Table.
