EVALUATION

Something seems to have changed which is not allowing side-effects in
shouldYieldFocus().  There is a workaround available.  Need to investigate more.
###@###.### 2001-12-05

A typical use case for shouldYieldFocus is to show a dialog.
In 1.4 showing a dialog would result in a focus trasfer and we again
ask the InputVerifier if it shouldYieldFocus which would show another dialog...
The fix is to NOT call into the InputVerifier if we have already called into
the InputVerifier.

WORK AROUND

    public boolean shouldYieldFocus(JComponent input) {
      if (verify(input)) {
        return true;
      }

      // According to the documentation should yield focus is allowed to cause
      // side effects.  So temporarily remove the input verifier on the text
      // field.
      input.setInputVerifier(null);
      System.out.println("Removed input verifier");

      // Pop up the message dialog.
      String message = "Roll over the 'JButton1' with mouse pointer "
        + "after closing this dialog.\nIt sometimes behaves correctly "
        + "for the first time\n but repeating action brings incorrect "
        + "behaviour of button.";
      JOptionPane.showMessageDialog(null, message , "invalid value", 
        JOptionPane.WARNING_MESSAGE);
      System.out.println("Showed message.");

      // Reinstall the input verifier.
      input.setInputVerifier(this);
      System.out.println("Reinstalled input verifier");

      // Tell whoever called us that we don't want to yeild focus.
      return false;
    }
