Erik,

Am I right when I say that you actually want to return a list of
dictionaries (tag value pairs)? In that case you should return
something like:
def getResults():
    return [ { 'Column2':'foo1', 'Column3','bar1'}, { 'Column2':'foo2',
'Column3','bar2'} ]

although I suppose you need an extra <dtml-with sequence_item> (I'm not very
much into DTML)

Hope this helps you in any way,
