Oh, now I understand. You're not using the framework; instead, you're
taking internal implementation details and expecting them to work out of
context.
Try something like this instead: run a typical form, and before any
queries are run, open a command window and type:
>>> b = self.PrimaryBizobj
>>> b.setFieldClause("*")
>>> b.setLimit(100)
>>> b.setOrderByClause("iid")
>>> b.requery()
>>> d1 = b.getDataSet()
>>> b.requery()
>>> d2 = b.getDataSet()
>>> print d1 == d2
True
If you get differences using the framework as it was designed to be
used, please let me know.
