/**
* 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.

// Component Creation and Initialization **********************************
/**
* 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)));
* </pre>
