Hi,

so the problem is when you select India on country box, you see cities getting populated; but if u select India once more you see the city list getting Appened to the list again?

How are you storing the list data for the comboBox? If you're using a Vector, you can call Vector.clear() then add your cities to it. Then I believe calling JComboBox.validate() will update the display with the new values.
