I have noticed that whenever I open the calendar, of the ice:selectInputDate and
select a day, or switch to another month or year, all of the forms, of the page,
will be updated, although the date doesn't affect the other forms. I've had a
look at the debug output (ctrl + shift + T) and compared the updated code to the
page source, before the update and there weren't any differences in the other
updated forms anyway. Just opening and closing the calendar however, doesn't
cause an update of all forms instead.

I'm experiencing the same behaviour (that all forms of the page get updated),
when I'm using the dataPaginator controls, when I switch the view of a
stackPanel, or when I click on a commandLink

What could be the reason, for updating more than the current form and how could
I avoid this, since this causes to reset all the scrollbar positions, of
scrolling panelGroups that are within forms and makes (all) the selectBoxes
flicker (in IE6), during the update process, besides the unnecessary traffic.

After trying this with OC4J 10.1.2 and 10.1.3, we tested it with Tomcat
and noticed that under Tomcat the same example doesn't cause a complete update
of the page, which would be correct.

So this seems to be a OC4J-Problem. But this Problem only occurs under
IceFaces1.5.
