I am running into a problem similar to what I have read here about inserted data and added data not showing up on jtable. I have tried repaint() and revalidate(), but to no avail.

Basically, I have two classes say A and B. A calls a function in class B to add a row of data to the table. Here is the code.(By the way I am using Netbeans 7.1.2 to add a table and then add some code to handle the update.)

public void callUpdateTable(){
    DefaultTableModel myModel = (DefaultTableModel)jTable1.getModel();
    DateFormat dateFormate = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
    Object[] str = new Object[3];
    Date date = new Date();  

    str[0] = dateFormate.format(date);
    str[1] = "Robot";
    str[2] = "hello"; 
    // myModel.addRow(str);
    myModel.insertRow(1, str);
    myModel.setValueAt("Hello", 1, 2);
    System.out.println("count = " + myModel.getValueAt(1, 2));
    jTable1.repaint();
}

The funny thing is on system print it prints out the value at the cell(1,2) I set the value, but doesn't show up on the table. Thank you for your help.
