form.vars appear only after form.process() call (process() -
filter/convert/format/validate request.vars to form.vars)
you have variants :
1. *before *form creation - modify field.default
2. *before* form.process() - modify request.vars -
request.vars.PostDate=...
3. pass your own set of vars - form.process(vars=myvars)
4. use form.process( onvalidation=myvalidation_fun) to modify form.vars *after
*basic validation passed
