It comes from this code in "Shared.DC.ZRDB.DA.DA.__call__":
if hasattr(self, 'aq_parent'):
## thus, "p" is either the parent or "None"
try: query=apply(self.template, (p,), argdata)
## this calls the template -- with "p" rather than "self"
## as "client"
## this explains why you can access the parents methods
## but not that of the Z SQL Method itself
I have no idea why this was implemented this way -- maybe
in order to be consistent with "DTML Methods"
They ignore the method itself and start
with the parent as top element on the DTML namespace.
