[mod_python] servlet form against publisher

I'm moving from publisher to servlet, because servlet are wonderful,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

but I'm get used at the publischer way to retrieve fields from a from.

 

Difference in retrieve fields from Form between publisher and servlet:

 

In publischer : req.form = util.FieldStorage(req, keep_blank_values=1)

In servlet : self.form = util.FieldStorage(self.req)       # the default for keep_blank_values is 0

 

So in servlet the fields not filled are not inserted in  self.form.list

 

Why this choice??

 

For example:

form with 2 fields: F1 and F2 

if I put 1 in F1 end 2 in F2 

and I would save automatically in self.session F1 and F2

after the submit F1= 1 and F2= 2

 

If I repeat the submit with F1=1 and F2=None, 

after the new submit still F1=1 and F2=2

 

because F2 isn't in the list and the last saved F2 in self.session is retrieved.

 

Is possible to put a class variable in servlet  for customize this choice?
