Ok, I see. That was not the "currentCD" reference I was talking about. I meant a persistent one that you kept at the class level.
You do need to create a CdwArtist object there to add it to the list. Perhaps we should just call that "newCD" to avoid confusion. Also, since the index is 0 based, it would be easier to initialize currCD with a value of -1 when you declare it, so your add code would be:

            newCD.setCdName(cdNameField.getText());    
            newCD.setItemNo(Integer.parseInt(itemField.getText());
            
                        <snip other sets>

            listModel.addElement(newCD);
            currCD = listModel.size()-1;    // set currCD to the index that was added
