I needed a documnt listener and try to add it using the normal event
extention in the javabeans to no avail so I resorted to the following
code which works but was wondering is there a better way?

private javax.swing.JTextArea getJTextAreaWordList() {
if (jTextAreaWordList == null) {
class documentListener implements DocumentListener {
public void changedUpdate(DocumentEvent arg0) {
System.out.println("changedUpdate");
}
public void insertUpdate(DocumentEvent arg0) {
System.out.println("insertUpdate");
}
public void removeUpdate(DocumentEvent arg0) {
System.out.println("removeUpdate");
}
}
jTextAreaWordList = new javax.swing.JTextArea();
jTextAreaWordList.getDocument().addDocumentListener
(new documentListener());
}
return jTextAreaWordList;
}

Thank in advance andre

DocumentListener is a special case in event handling, as it acts on the
text area's document, rather than the text area itself (as seen in your
code.) Currently there is no work around for introspecting situations
like this, when important events are invoked on a property of a bean.
For now, coding by hand is required in this case.
