JFileChooser doesn't close?

Question

Hi All,
I'm working on an application which has a button actionlistener that calls a method to open a file using FileChooser. I can click the button and get the filechooser dialog box and select a file, but then the filechooser seems to be repeating - it pops up again!
Am I missing something? One click = one action, right?
Confused....
Here's the code:
     // Action Listener methods
     public void actionPerformed(ActionEvent event)
          if(event.getSource()==btnExit) {
               if(brInFile!=null)
                    try
                         brInFile.close();
                    catch(IOException ioe) {}
               System.exit(0);
          else if(event.getSource()==btnOpenInputFile) {
               readInFile();
     public void readInFile()
          String strInFile = "";
          JFileChooser jfc = new JFileChooser();
          if(jfc.showOpenDialog(this)!=JFileChooser.CANCEL_OPTION)
               try
                    brInFile = new BufferedReader(new FileReader(jfc.getSelectedFile()));
               catch(FileNotFoundException fnfe)
                    JOptionPane.showMessageDialog(this,"File Not Found!");
     }

Well, the code you posted gives no clues as to why this is occurring. One possibility is that you are adding the same listener to the Button twice. This would cause the problem you are getting. Try inserting a line to print out all of the listeners registered with the button when the actionPerformed method is invoked.
