Oh, I'm sorry. I found that problem but I forget to write.

XOOPS 2.2 lost Caleneder scripts, You need to copy from XOOPS 2.0.x sources.

coping follow 3 files into XOOPS_ROOT_PATH/include,
xoops-2.0.x/html/include/calendar-blue.css
xoops-2.0.x/html/include/include/calendarjs.php
xoops-2.0.x/html/include/include/calendar.js
