You found something like that in my book?

  Then, apparently, I need to change something.

  It is not a "bigger" problem to address an object!

  You use "Computed Attribute Access", "Computed Variable/Object Access"
  or "restrictedTraverse". All not too difficult....

Here you use both "Computed Object Access" *AND* "restrictedTraverse".
Use just one, not both:

     <dtml-with expr="restrictedTraverse(working_folder)">
or
     <dtml-with expr="_.getitem(working_folder)">

You read in my book the difference between "_.getitem(...)",
and "_[...]"? You already understand why to use "getitem"
rather than subscription?
