This item has been discussed on the list previously, and as I think
about it now, this is normal HTML behavior. In my web development of
forms in plain HTML, I always had to insert a non-value entry first that
instructed the user to select an entry to get around this HTML behavior.
I think the same should be done in your Qooxdoo code to avoid non-
standard behaviors with single-height picklists. Otherwise, you risk
confusing the user who is used to seeing the standard behavior of the
first entry being the default entry.
