Why is the Popup Menu Appearing Twice When I Add a Color?

SUMMARY

The issue of the popup menu appearing twice when adding a color is caused by the action listener being added twice to the button. The user instantiated the button and added the action listener during both instantiation and when adding the button to the panel. This redundancy leads to the event being triggered twice. The solution is to ensure that the action listener is only added once to prevent duplicate events.

Code:
        else if(e.getSource() == add)
        {
            try{
                int redInt = Integer.parseInt(red.getText());
                int greenInt = Integer.parseInt(green.getText());
                int blueInt = Integer.parseInt(blue.getText());
                String s = (String)JOptionPane.showInputDialog("Enter Your Color Name");

                colorPane.addColor(redInt, greenInt,blueInt, s);
            }
            catch(Exception ex)
            {
                System.out.println("You must enter a number in all fields!");               
            }
           
        }

I call this with a button (add) and it all works fine, however, when I hit ok, it adds the color, but brings the menu popup back as if I had just hit the add button. If you hit ok the second time, though, it goes away. What am I missing? If you need any other code snippets let me know.

Disregard. I added my action listener twice. Once when I instantiated the buttons and a second time when I added the buttons to the panel.

The try block is expecting you to enter a string for the color name. Are you doing this? Hitting the OK button could be setting s to an empty string, which could be causing problems with the addColor() function.

Edit: Never mind, as the problem seems to be figured out.
