I am using hybrid exposed filters (), or Grouped filter and have some troubles with it.
I make some grouped (hybrid) filters with checkboxes (e.g. rooms: 1 (=1), 2 (=2), 3+ (>=3), optional, allowed multiple selection, radiobuttons/checkboxes).
When I submit exposed form all works fine, but when none of checkboxes in this filter selected all works only on first page: in url there are none of arguments of this filter (viewspage?myotherargs=somevars), but pager produce url for next pages like this: viewspage?rooms=0&rooms=0&rooms=0&rooms=0&myotherargs=somevars&page=1. So, the second page of view's result is empty with error "An illegal choice has been detected" and checkboxes become selected all.
When I remove wrong part of query rooms=0&rooms=0&rooms=0&rooms=0 from url, the view show normal result page. If I restrict multiple selection, checkboxes become radiobuttons with "Any" value by default, and it works fine too on second and other pages.
