Show model properties in visual components

Question

Hi,
My application has a model Track object with some properties like artist, title, album, ...
When a track is selected in a table, it's properties are shown in another JPanel composed with JTextField components.
For this purpose I have implemented the Observer pattern where every JTextField components implement a TrackSelectedEventListener to show a
specific property.
This approach is working fine, but the only drawback of it is that I needed to create a new Component that extends JTextField for each textfield
that implements TrackSelectedEventListener, which leaves me with a fair amount of custom components just for this purpose.
This made me thinking if there is another, maybe better? approach (apart from bean binding).

Ok thx for the reply.
But about the "only 1 JTextField subclass needed" remark:
Let's say we have 3 textfields, 1 to display the title, 1 to display the artist, 1 to display the album.
Now if I create 1 JTextField subclass which implements a listener to update the value of the textfields whenever a track is
selected like this:
public class PropertyTextField extends JTextField implements EditTrackEventListener {
     private static final long serialVersionUID = 1L;
     @Override
     public void editTrackEventOccurred(EditTrackEvent event) {
           setText("custom text for title, artist, album");     
}As I see it, the editTrackEventOccurred(EditTrackEvent event) implementation is custom for each of the textfields (title, artist, album)?
So I guess this means that I need to make a custom component for each of the textfields?
Or am I missing something?
