Thanks for your comments, Roedy.

In my real program I have added lots of System.out.println's from
which I could tell that everything was working as expected and that
the selected object was updated except that the new selected object
was not shown in the JComboBox.
I have found out in the meantime that I simply need to fire an event
in my setSelectedItem method of the CombinedListModel class . Makes
sense that the JComboBox will not update its view when the
setSelectedItem method is invoked by bypassing the JComboBox. Here is
the new version. It seems to be working but is not throughly tested.
To do the testing I will have to remove that changes that I made
yesterday when desperately looking for the source of the unexpected
behaviour.
<code>
public void setSelectedItem(Object item){
    System.out.println("Selection changed");
    if(items.contains(item)){
        selected =item;
 
fireContentsChanged(this,items.indexOf(item),items.indexOf(item));
    }
    else{
        System.out.println("Selection not possible");
    }
}
</code>
Regards
Piet
