According to the Tapestry docs for DateField:

"One wierd aspect here is that, because client-side JavaScript formatting
and parsing is so limited, we (currently) use Ajax to send the user's
input to the server for parsing (before raising the popup) and formatting
(after closing the popup). Weird and inefficient, but easier than writing
client-side JavaScript for that purpose."

Seemingly the serverside formatting is failing, and a container's zone is
getting refreshed instead.  Tomorrow I may delve into how "async=true"
works when zones are nested.  I assume nested zones are allowable?

Chris.

Yes, DateField uses AJAX, but not zones, so, if a DateField is causing an
AJAX update, that's definitely a problem there.

Yes, nested zones are allowed.
