Hey Andrew,

Cool tip. I never took advantage of this stuff:

<form action="pyUpdateRecords" name="theform" method="post">
   <input type="text" name="items.id:records" value="023">
   <input type="text" name="items.lname:records" value="smith">
   <input type="text" name="items.fname:records" value="frank">
   <input type="text" name="items.id:records" value="583">
  <input type="text" name="items.lname:records" value="gates">
   <input type="text" name="items.fname:records" value="bill">

When this form is summited it puts the following array of dictionaries 
in the request: 

items[{'fname': 'frank', 'id': '023', 'lname': 'smith'}, {'fname': 
'bill', 'id': '583', 'lname': 'gates'}]

Then the records can be updated like so:

#module pyUpdateRecords

for item in request.get('items',[]).
    context.SQL.upDateMyRecs(id=item['id'],lname=item['lname'] ....)
# now return a screen
return context.SomeTemplate(context,request)
