Rails - Aug 2006 - Hrm, :after on auto_complete_field helper ?

Okay, urm, here is the problem :)

I have an auto_complete field that gets back a set of three values, so, 
ideally, I thought I would put the :after tag on the 
auto_complete_field, use a little custom javascript function that splits 
it up and flings it into the other values, except, call me stupid, but, 
auto_complete_field doesn''t have an :after tag ? At least, I
can''t see
it in the API ..

So, any idea''s on how todo this ? I am open to suggestions ;)

Regards and Thanks
Stef
