Hi all,

I'm on Linux, Odoo12c. After recent 'git pull' and 'odoo -u all' I get following error when trying to display calendar view of the tasks.

AFAIK the date_start is commonly used attribute, and did not change it. Any clue what I'm missing here please?

Error: Calendar view has not defined 'date_start' attribute.
