How to programmatically set first day of week in DateItem?

[fhisg]

DateChooser has a setFirstDayOfWeek(int) method - DateItem hasn't :-(

Furthermore, since there is a bug for DateItem with German locales (http://code.google.com/p/smartgwt/issues/detail?id=679) the date picker shows the wrong first day of week. So, how can I set the first day of week programmatically on DateItem?

Use DateChooser.setDefaultProperties() to set this system-wide.

Oh, right, forgot about that method. However, patching (i.e. correcting) SmartGwtMessages_de.properties as proposed in the bug report at Google Code fixes it, too. Would be nice if that fix made it into 3.1 final.
