An editable JComboBox will change newlines into spaces for selected items and
for pasted-in (cut and paste) text. This is not acceptable behavior. I'm using
JComboBoxes for a "find" function, and the user must be able to search for
newlines. The correct behavior would be to show the newline as a square, as is
done in the pulldown list. That is also the way Motif, for example, handles it.
This was broken in 1.3.1 also, but in a nicer way - multiple lines were shown
(the bug was visual rather than functional). Example code follows - select the
second item or paste in a newline.


   import javax.swing.*;

   public class JComboBoxBug {
   
      public static void main(String args[]) {
         JDialog dialog = new JDialog();
         JComboBox cb = new JComboBox();
         cb.setEditable(true);
         cb.addItem("test");
         cb.addItem("line1\nline2");
         dialog.getContentPane().add(cb);
         dialog.pack();
         dialog.setVisible(true);
      }
   
   }
