[Zope] PersistentMapping not persistent?

[alex@quad.com.ar]

ok, here's a simplified view of my object

__init__(self):
   self.data=PersistentMapping()

createUser(self,user,password,roles=[]):
   self.data[username]={'username': username, 'password': password, 'roles':
roles}

updateUser(self,username,password, roles):
   self.data[username]['roles']=roles
   if password: self.data[username]['password']=password

there's a lot more on the object as you would guess, but that's the relevant
code to my problem.
both create and update works.. but after updating a user password and/or
roles the changes only last for a while, and as I said, if I replace all
this with a self.data={} and signaling with self._p_changed then everything
works fine.

can you see any potential problem in that code?

Thanks for the help

Alex
