Implementation of invisibles in search view altered handling of search inputs: their parent may not be the searchview anymore (usually is a instance.web.search.Group). GroupbyGroup assumed parent was view and was actually unused until xmo@openerp.com-20130307124222-1ypzfopbktxmad4z, which exposed the incorrect underlying assumption. Make GroupbyGroup access its view when it wants its view, not its parent. bzr revid: xmo@openerp.com-20130312092824-z7sh4h3ityo4g00v
