This demo shows a periodic updating component inside of another update component. This presents a complication in that refreshing the outer component will not automatically be able to stop the updater in the inner component, which will cause refresh threads to pile up (eventually resulting in a backtrack exception as the ajax cache gets blown out). The workaround for this (for right now, at least) is to call the "Stop" function for the periodic updating component when the update operation is done.

update outer / update inner
Content above = Auto update = Content below.
