Could the ZODB simply be lazy about re-populating the object attributes
until you first cause a "getattr" by trying to look at one of them?  Try
adjusting that last method of yours to this:
    def getJobs(self):
        lst = list()
        for id, job in self.context['accounting'].items():
            print id, job.__dict__
            try:
                a = job.a
            except AttributeError:
                pass
            print id, job.__dict__
            lst.append(job.__dict__.copy())
        return lst
If ZODB efficient/lazy loading is the problem, then the second "print"
statement should find the attributes populated.
