Doublebox eating the decimal point

Hi matze,

No, it was not the grouping point. Because when I inputted "2.5" it showed "2.5" correctly, when I inputted "2" it showed "20", in en_US locale the grouping point is ",".
Also, this happens when setting the doubleboxes from server side. Just inputting the values from keyboard works nice.

Now, another issue that took me a while to think "hey, might be just a doubleblex issue..."

I have two doubleboxes, when one changes, the other way may, or may not change. This is done on server side, which works.
Now I'm moving this logic to client side, which is quite simple, but with doublebox just don't work, the value is not updated at server side. Replacing doublebox with intbox works as expected.
With more testing, I got the conclusion that if you use doublebox, to support floating point values, you HAVE to use the decimal separator, otherwise things will go wrong.

Here is an exemple. Input 1 on the kbd, then click on the button. The value on server side is null. Now input "1.5", then click on the btn, then it works. I'm pretty confident that this is a bug, right?

<zk xmlns:w="http://www.zkoss.org/2005/zk/client">
    <doublebox id="from" w:onChange="changeValue(this);" format="0.#"/>
    <doublebox id="to" format="0.#"/>
    <button label="Test to on server side" onClick="alert(to.getValue())"/>
    <script>
        function changeValue(cmp) {
            var to = cmp.$f('to');
            to.setValue(cmp.getValue());
            to.smartUpdate('value', cmp.getValue());
        }
    </script> 
</zk>
