[web2py] request.vars problem

[Manuele Pesenti]

Hi *,
I'm trying pass some variables from one one controller/function to 
another using the command:

URL(request.application, 'myControler', 'myFunction', 
vars=dict(myVar=myVar))

but when I call request.vars.myVar I get a string type object even if 
myVar was a dictionary. I cannot bypass this problem using the json 
library because it causes an early return of the function. I tried:

import gluon.contrib.simplejson as sj

myVar = request.vars.myVar
myVar = sj.loads(myVar)

and after that any command are not executed... any suggestion?

thank you in advance
Bye
