An easy patch... but I rather do not patch at all... I may be forced to w=
ork=20
with unpatched Zope release.

I think I'll convert :records to a list of tuples...=20

IMHO :records usefulness is quite limited because it is not mutable and=20
because it hinders iteration over <dtml-in>dtml-call APythonScript></dtml=
-in>=20
unless you pass it as a parameter. But I am very inexperienced Zoper.

AFAIK :records are useful in the web form itself to gather data.. and you=
 can=20
feed :records into ZSQL directly for data rows insertion... and that's ab=
out=20
it. If you need more, you should convert :records into some standard Pyth=
on=20
data structure that you can flexibly work with.

Please correct me if I'm wrong.
