problem when adding a new row into xTable interactivly using vector
There are two screens involved. On one screen, it displays the xTable. On xTable screen, there is a button called "add new item". After clicking "add new item", a pop up window comes up (this is the other screen). On the pop up window, you can input the values for the provided text fields. After input, click the button "add". The added values are supposed to display on the xTable.
But I am facing to difficulty to display the added values on the xTable. The added values are not shown on the xTable. Also the vector is not adding the new value continuously. When I add first time, the vector size became 1. But when I continuously add new items, the vector size remains 1.
Can anybody help me with that? Thank you.
Here is my code:

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = getSize();
setLocation(new Point((screenSize.width - frameSize.width) / 2,
(screenSize.height - frameSize.height) / 2));
tableModel =new PumpFoodTableModel();
xTable1.setModel(tableModel);
tableModel.addTableModelListener(xTable1);
}
