I was doing some dict modifing like testvar = {'test1':{'test2':'test2value'}} so, everything was nice until I hit my browsers refresh button as fast as I could and my little method which did some if not testvar.has_key('test1') wrote my default values to my testvar tried setting self._p_changed = 1 but after some time(usually sooner) my values disapear and after zope restart they even don't exist anymore :( Tried PersistentMapping, that also didn't help much :(

any suggestions?

Read the ZODB3 documentation. Try to understand how ZODB persistence works. -- Dieter
