Hi,
If I add the same reference of a ActionListener twice to a component then the actionPerformed method will be called twice for each action on that component ?
If yes if I remove the action listener as below will it remove both the listeners ?
myJcomboBox.addActionListener(myActionListener);
myJcomboBox.addActionListener(myActionListener);
Then remove the listener as below
myJcomboBox.removeActionListener(myActionListener);
Please clarify how this will work.

That sounds like the sort of thing you could write a program to test.

You'd better make sure any listener is only added once, to prevent having to answer this question.
