Calendars not updating in ZWC

[goppegard]

I've got an issue with calendars not updating for users of a specific domain after upgrading to 5.0.15.

When creating a new appointment in ZWC (advanced version), it doesn't show up immediately. I've verified the appointment is created via CreateCalendarItem in mailbox.log. When I hit the Refresh button in ZWC (GetMiniCalRequest in mailbox.log generated) it doesn't show either. However, when I search all appointments (SearchRequest in mailbox.log) with an empty criteria, the calendar updates and the appointment shows.

The same behavior occurs when deleting the appointment (doesn't disappear from ZWC, Refresh doesn't remove it, but searching does correctly update ZWC).

In ZWC standard version, all appointments show up as expected. I've only seen this problem with users on a specific domain; it doesn't appear to be server-wide.

I've flushed cache and cookies from firefox. Any ideas?

After talking to Zimbra support, it appears to be this bug: Bug 35297 – week view of calendar goes blank

Waiting on 5.0.16 for a fix.
