I'm trying to migrate the old caldav system to version 7.0 based on the provided modules in the openerp extra-addons branch.

The main issue for now is, that task synchronisation isn't working bidirectional. I can import my task from OERP to e.g. Thunderbird, but not vice versa. In fact TB states that my OERP Calendar is not supporting tasks. (Event synchronisation is working in both directions.)

Is this a known fact from v6.x? Or am I just doing something wrong?

Any additional information about caldav for OpenERP is also appreciated.

EDIT:

Apparently CalDAV for OpenERP manages events and tasks in different calendars, and sets the supported-calendar-component-set for the calendar to the basic.calendar.type.

Any idea on why that' so or how to use one calendar for both?

Thanks.
