JFormattedTextField with edit and display formatter for date

Question

How can I have a date display formatter and a edit mask date formatter for JFormattedTextField instance.
When I do
               DateFormatter dateFormatter = new DateFormatter(new SimpleDateFormat("dd/MM/yyyy"));
               JFormattedTextField.AbstractFormatterFactory factory = new DefaultFormatterFactory(dateFormatter, dateFormatter, dateFormatter);
               jFormattedTextField_2.setFormatterFactory(factory);
all is okie but I wanna a mask formatter and if I do
               DateFormatter dateFormatter = new DateFormatter(new SimpleDateFormat("dd/MM/yyyy"));
               MaskFormatter editFormater = new MaskFormatter();
               try {
                    editFormater.setMask("##/##/####");
               } catch (ParseException e) {
                    e.printStackTrace();
               editFormater.setPlaceholderCharacter('_');               
               JFormattedTextField.AbstractFormatterFactory factory = new DefaultFormatterFactory(dateFormatter, dateFormatter, editFormater);
               jFormattedTextField_2.setFormatterFactory(factory);
jFormattedTextField_2 accepts invalid date.
What can I do to have a date edit mask and a date display mask for a
JFormattedTextField instance.
Thx a lot, Tony.

txtdatnalzaproizvoid = new JFormattedTextField(datformater("##/##/##"));
txtdatnalzaproizvoid.setValue(datumformat());
public static MaskFormatter datformater(String formatnavnes){
MaskFormatter formatter = null;
try {
formatter = new MaskFormatter(formatnavnes);
formatter.setValidCharacters("0123456789");
} catch (java.text.ParseException exc) {
System.err.println("formatter is bad: " + exc.getMessage());
System.exit(-1);
return formatter;
public static String datumformat(){
Date dddd = new Date();
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yy");
datumformat = formatter.format(dddd);
return datumformat;
}
