Ok, thank you anyway. You were telling me twice what I already knew and as if you had not read my question. I think I was clear I wanted to set ALL locale-dependent calendar/datetimeinput settings in a culture and wanted to inform you there is a bug in submitting the culture setting, namely the calendars.standard.firstDay, to a calendar/datetimeinput property, namely the firstDayOfWeek . All other calendar settings are successfully submitted from culture to widget properties. But never mind, forget it.
