/**
 * Demonstrates a "hand-made" way how to connect a master list with a bound 
 * details view. It builds a JList of Albums with an attached details panel 
 * that presents the current Album selection. The details panel's components 
 * are bound to the domain using ValueModels returned by a PresentationModel.<p>
 * 
 * This example handles selection changes with a custom ListSelectionListener,
 * the AlbumSelectionHandler, that sets the JList's selected values as new
 * bean of the details PresentationModel. A simpler means to achieve the same
 * effect is demonstrated by the MasterDetailsSelectionInListExample that uses
 * the SelectionInList as bean channel for the details PresentationModel.<p>
 * 
 * Another variant of this example is the MasterDetailsCopyingExample
 * that copies the details data on list selection changes, instead of binding
 * the details UI components to the details PresentationModel's ValueModels.

    /**
     * Creates, binds, and configures the UI components.
     * All components in the details view are read-only.<p>
     * 
     * The coding style used here is based on standard Swing components.
     * Therefore we can create and bind the components in one step.
     * And that's the purpose of the BasicComponentFactory class.<p>
     * 
     * If you need to bind custom components, for example MyTextField, 
     * MyCheckBox, MyComboBox, you can use the more basic Bindings class.
     * The code would then read:<pre>
     * titleField = new MyTextField();
     * Bindings.bind(titleField, 
     *               detailsModel.getModel(Album.PROPERTYNAME_TITLE));
     * </pre><p>
     * 
     * I strongly recommend to use either the BasicComponentFactory or 
     * the Bindings class. These classes hide details of the binding.
     * So you better <em>not</em> write the following code:<pre>
     * titleField = new JTextField();
     * titleField.setDocument(new DocumentAdapter(
     *     detailsModel.getModel(Album.PROPERTYNAME_TITLE)));
