Because the Add/Create button is global, it's not really possible to know *where* to create the new record, and the current design can't really deal with a record being edited outside of all groups. An option might be to create a dedicated empty group for that, but the cost/benefit is high and the UI would probably be odd. lp bug: https://launchpad.net/bugs/1098205 fixed bzr revid: xmo@openerp.com-20130306102136-2ms7llbt4swka92k
