I think the easisiest way would be making your
http://www.symfony-project.org/api/1_2/sfValidatorSchema
accepting as a first argument the array of the checkbox fields names
and, in "doClean" method validating that at least one is checked (and
use this as a post validator). I've never implemented something
similar so take my words just as "this is the way I'd go" and not as
"I'm sure this is the best way" :-)
