This happens when DateField's resolution is SECOND, MINUTE or HOUR and popup calendar shows time, and it's initialized with a Locale that has 24h time format and then changed later to a Locale that has 12h time format.

When the locale has changed to 12h format, and user tries to open the popup window, nothing shows up. NullPointerException is thrown on client side.

Looks like VCalendarPanel.VTime.ampm ListBox widget is not checked and initialized when switching to 12h format.

Here's the stacktrace:
