Hi, Jaime,

the only way to do this with twill is to do the calculation yourself --
that is, to write an extension function in Python that mimics the
output of the onChange call.  As a simple example,

-- file 'date_extension.py' --

def fill_date_field(mm, dd, yy):
   date_str = "%s/%s/%s" % (mm, dd, yy)
   twill.commands.fv(1, 'hidden_field', date_str)

--

then in twill,

>> extend_with date_extension
>> fill_date_field 6 7 2006

It's cumbersome, I know ;(.  Let me know if you need any help navigating
the Python datetime module documentation...

cheers,
