Hi people,

I have an application that is being used in production almost one year. 
Today I was making an update in local development environemnt and got the 
error below. I tried to use other functions where the SQLFORM.grid is used 
too and got the same error. 

Traceback (most recent call last):
  File "/home/andre/Projetos/web2py/gluon/restricted.py", line 219, in 
restricted
    exec(ccode, environment)
  File "/home/andre/Projetos/web2py/applications/nwproducao/controllers/adm.py"

  File "/home/andre/Projetos/web2py/gluon/sqlhtml.py", line 2859, in grid
    page = safe_int(request.vars.page, 1) - 1
  File "/home/andre/Projetos/web2py/gluon/sqlhtml.py", line 108, in safe_int
    return int(x)
TypeError: int() argument must be a string or a number, not 'NoneType'


Thanks for your help.
