i have problem with JComboBox in my program.
i am adding items to JComboBox at the time of itemStateChanged of a JRadioButton.
Every time the selected JRadioButton is changed, i am changing the JComboBox items.
i am retrieving the selected JComboBox item at the time of JButton click.
But i got only the null value.
i have also used another JComboBox. The items for this JComboBox is added only at the time of constructig the object. When i selected an item in this JComboBox i get the selected value correctly.
What is the problem with the first JComboBox?
i need the immediate reply.
thank you.

In this case, we cannot imagine how your code behaves, without having a look at your code. Could you provide us a portion of your code so that we can figure out what is wrong with the code...

I guess the problem would be in the way you use the method of fetching the values from the JComboBox...
