Use value attributes in there. See below.
> </select>
> </form>
> <div id="id2""></div>
Lose the extra quote, too. Won't imped 'cuz the browser is forgiving,
but still.
Your issue lies with Prototype 1.4 code not dealing properly with
unspecified value attributes for <select>:
opt = element.options[index];
value = opt.value;
if (!value && !('value' in opt))
value = opt.text;
You see, a non-specified value attribute yields value == '', which
bool-equates to false. But the subtest ('value' in opt) will always be
true, as the DOM node *always* features this property. So you never
revert back to opt.text. As both your options yield the same value
(''), there's no change detected by the Observer.
I suggest getting Prototype from the trunk (or if you're not keen on
SVN, just get script.aculo.us and snatch its prototype.js file) for now,
which deals with missing values.
I also submitted a patch recently for ol' bug #5033 [1], that
distinguishes between unspecified attribute and empty-valued attribute.
But that's not necessary for you: use non-empty value attributes, and
use a more recent prototype.js file.
