JSpinner text not updating

[Mike Southgate]

I have a JSpinner with a SpinnerDateModel on a screen that scrolls through various database records. First time through, the date shows up fine. When the database record changes, though, the text displayed doesn't change. This is what I'm doing:
In my constructor:

private SpinnerModel spnrMdl;
private JSpinner spnr;

In a method triggered by my constructor and an actionlistener:

      if (run.getRunId() <= 0) {
         spnr = new JSpinner();
      } else {
      System.out.println("run ts " + run.getRunTS().toString());
         spnrMdl = new SpinnerDateModel(run.getRunTS(), null, new Date(),
                                  Calendar.DAY_OF_MONTH);
         spnr = new JSpinner(spnrMdl);
      }  //if
  

Thanks in advance for your help

If you're going to make a new SpinnerDateModel and new JSpinner for every call you'll have to remove the old spinner from your gui and add the new one in it's place. Changing the spinner that the reference (member variable) spnr points to has no affect on what your gui is using.

Since you are only changing the value in the SpinnerDateModel you could avoid the expense of making new components and adding/removing/validating by resetting your model. Call setValue(run.getRunTS()) on your SpinnerDateModel.

Wow, that was pretty obvious once it was pointed out to me. Thanks, Craig, I'd spent several hours fighting with it and did try setValue, I just did it on the new spnr!

thanks again
