-/**
- * This javax.swing.ComboBoxModel can be used to keep a ListDataListener
- * (e.g. a JComboBox) in synch with a ListValueModel (or a CollectionValueModel).
- * For combo boxes, the model object that holds the current selection is
- * typically a different model object than the one that holds the collection
- * of choices.
- *
- * For example, a MWReference (the selectionOwner) has an attribute
- * "sourceTable" (the collectionOwner)
- * which holds on to a collection of MWDatabaseFields. When the selection
- * is changed this model will keep the listeners aware of the changes.
- * The inherited list model will keep its listeners aware of changes to the
- * collection model
- *
- * In addition to the collection holder required by the superclass,
- * an instance of this ComboBoxModel must be supplied with a
- * selection holder, which is a PropertyValueModel that provides access
- * to the selection (typically a PropertyAspectAdapter).
