AHHHHHH! Multiple open file chooser windows

Question

Ok, I am going nuts here. I have figured out the problem of getting the data to appear on the same frame that I originally open. The menu at the top has File -> Open. When the user first comes into the form, that is the only thing enabled. I am using a different file opener for this initial opening. Here is why (although, it doesn't fix the problem):
When the user opens the file, the data appears in the frame. If the user opens another file, the data appears in the frame and another file open chooser window appears even though the users did not select it again. If the user then opens another file, then that is it. If the user then goes to the menu and selects File->Open the file open chooser appears. The user selects a file and the data appears in the frame, but another file open chooser appears. I have had it happen up to 8 times. Now, I have no idea why this is getting called over and over again. It is this that is being called multiple times:
       jMenuFileOpen.addActionListener(new ActionListener()  {
        public void actionPerformed(ActionEvent e) {
          System.out.println("IS THIS THE OPEN THAT IS CALLED OVER AND OVER AND OVER AGAIN");
          jMenuFileOpen_actionPerformed(e);
      });That println is printing each time another file open chooser window appears. I am pulling out my hair trying to figure this one out. The way I am starting this up is this:
  public FDASFrame(File file) {
    enableEvents(AWTEvent.WINDOW_EVENT_MASK);
    inputfile = file;
    try {
      jbInit();
    catch(Exception e) {
      e.printStackTrace();
  public void setFile (File file) {
    enableEvents(AWTEvent.WINDOW_EVENT_MASK);
    inputfile = file;
    try {
      jbInit();
    catch(Exception e) {
      e.printStackTrace();
  }These methods are in the main frame - FDASFrame. I am wondering if that is the problem. Here is the part of the filechooser that calls the main frame when the file is gotten:
            parent.setFile(file);
            JFrame frame = (JFrame)parent;Has anyone got any ideas to this problem? It might solve the problem of the tables getting duplicate data in them, too, each time a new file is opened.
Thanks to anyone who has any ideas on how to solve this. I am stumped.

}I know I should split this out and I will sometime, but for now, this is the way the code is.
I think the reason that nothing is coming up is that all my work is done in jbInit(). I don't want to post that code, but I will if needed. So, if I can only call it once, then how do I get the rest of it to run? Maybe I am going about this all wrong. But if it is not in jbInit(), then how does it get called? I guess now, I am confused.
Thanks for the help.
