Sean -

I've skimmed over the two messages you referenced, and it wasn't very 
apparent what the problem is mainly due to the complexity of the 
attributes. I think if you want this resolved, you need to work on a clean 
and simple case explaining how to replicate the problem. Assume that we, 
the folks who develop mod_python, are not that smart actually, and we 
don't know what SimpleTAL is and have the attention span of a first grader
