Summary Changes to aria-hidden don't change VO navigation

Reported 2011-09-07 11:45:44 PDT
Using JS to update aria-hidden attributes doesn't appear to change the VO navigation. For example, toggling the attribute (or lack thereof) on a list of items doesn't change the item that gets read when navigating the list.

Looks like the problem was when a parent asked for it's children, the children may not have been told to re-update their own caches. The result was that stale children information might be propagated. The fix is to always clear the children first. This ensures the parent always has the most up to date information
