How to create Using Formatted Text Field with multiple Sliders?

Question

Hi i found the Java Sun tutorial at http://java.sun.com/docs/books/tutorial/uiswing/components/slider.html very useful, and it tells how to create one Formatted Text Field with a Slider - however i need to create Formatted Text Field for multiple Sliders in one GUI, how do i do this?
my code now is as follows, and the way it is now is scroll first slider is okay but scrolling second slider also changes value of text field of first slider! homework due tomorrow, please kindly help!
// constructor
label1 = new JLabel( "Individuals" );
scroller1 = new JSlider( SwingConstants.HORIZONTAL,     0, 100, 10 );
scroller1.setMajorTickSpacing( 10 );
scroller1.setMinorTickSpacing( 1 );
scroller1.setPaintTicks( true );
scroller1.setPaintLabels( true );
scroller1.addChangeListener(this);
java.text.NumberFormat numberFormat = java.text.NumberFormat.getIntegerInstance();
NumberFormatter formatter = new NumberFormatter(numberFormat);
        formatter.setMinimum(new Integer(0));
        formatter.setMaximum(new Integer(100));
textField1 = new JFormattedTextField(formatter);
textField1.setValue(new Integer(10)); //FPS_INIT
textField1.setColumns(1); //get some space
textField1.addPropertyChangeListener(this);
//React when the user presses Enter.
textField1.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0),  "check");
        textField1.getActionMap().put("check", new AbstractAction() {
            public void actionPerformed(ActionEvent e) {
                if (!textField1.isEditValid()) { //The text is invalid.
                    Toolkit.getDefaultToolkit().beep();
                    textField1.selectAll();
                } else try {                    //The text is valid,
                    textField1.commitEdit();     //so use it.
                } catch (java.text.ParseException exc) { }

              if(source==scroller1)   {
                   System.out.println("source ==scoller1\n");
                   textField1.setValue(new Integer(fps)); //update ftf value
              else if(source==scroller2)     {

                   textField2.setValue(new Integer(fps)); //update ftf value
         } else { //value is adjusting; just set the text
             if(source==scroller1)     textField1.setText(String.valueOf(fps));

Answer 1

if :p3_note_id is null
then
insert into notes (project_id, note, notes_month, notes_year) So, p3_note_id is NULL.
Another option is that you have a trigger on table NOTES that generates a new note_id even for an update.
