The listeners are coming from the GUI element itself. A JList automatically 
attaches a ListDataListener to the model and a ListSelectionListener to the 
selection model. The same applies to the JTable.
So basically what I do is provide a model that is wrapped once in a TableModel 
and also wrapped in a ListModel. Those models are then attached to either JList 
and JTable. While being 2 different model object they wrap the same model in the 
background. Additionally I create a DefaultListSelectionModel add attach them to 
the table and the list
So again, what happens is. When I e.g. add an item to the main model. Both the 
table and the list are notified since they attached 
ListDataListeners/TableModelListener to the model. Additionally they internally 
notify the selection model because there was an item added and therefore some 
selections might need to be moved one up. But since both table and list do this
selections are moved up twice.
