Notes field does not clear when you navigate with < > in flight editor mode

[reevery]

Hi. I was editing some flights today using the GUI. I noticed that when you start with a flight with notes, then navigate to the previous or next using the navigation buttons < or >, the notes field does not clear. That means, if you save the next flight, you save the notes from the previous flight to every other until you notice.

It's not just </>; if you click edit on one, exit, and then edit on another that doesn't have a note set... that note will also load...

I suspect the issue is related to this:

  if(col[16] != "") {
    $('note').style.color = '#000';
    form.note.value = col[16];
  } else {
    $('note').value = $('note').hintText;
  }

The else case was removed when doing some refactoring of the hinted text boxes. In the old version, if the column from the DB was not "", we set the text, falling back to the hint text. This isn't needed now, so we don't clear the state properly... Easily fixed at least.
