In order for hash to work:
1) In the model it has to be initialized (use symbols here , :en, :jp)
class Bgroup
   property   :title,    Hash
   def initialize
     @title = Hash.new
     @title[:en] = @title[:jp] = nil

2) in the template use " and not ' for the name definition, and not 
symbols, just plain strings (populate @bgroup for edit case)
<input id="bgroup_title[en]" name="title[en]" value=@bgroup.title[:en] />
<input id="bgroup_title[jp]" name="title[jp]" value=@bgroup.title[:jp] />
(the name="title[en]" is returned as "title" => {"en" => "inputed value", 
"jp" => "inputed other value" }   )

3) in the controller manually assign the values. fill function does not 
work correctly with Hash, that is also why Date is not stored with fill
(I guess...)
def bgroup_save(meth = 'new')
   if request.post?
     if meth == 'new'
       bgroup = Bgroup.new
     elsif meth == 'update'
       oid = request['oid']
       bgroup = Bgroup[oid]
#    request.fill(bgroup)
     bgroup.title[:en] = request['title']['en']
     bgroup.title[:jp] = request['title']['jp']
     bgroup.creation = Date.new(request['creation']['year'].to_i,
   expire_output 'bgroups'

Sorry for the NOT ELEGANT solution, but until fill is updated to handle 
Hash better this will do.. ;-)
