[Zope] Manipulating Structured Text Document using Tree.py

[Colin Leath]

Hello,
I'm attempting to create an expandable/collapsible tree type document
(e.g. msword outline style) from the body of CMFDocument containing
structured text. For some background please visit:
http://lists.zope.org/pipermail/zope-cmf/2002-September/015096.html

Below, I've pasted the External Method I've been working on, which
instead of the EditableBody of CMFDocument is using a file on
filesystem containing STX.

My problem is that I'm getting the following error:

[Which occurs when the following call is made:
     tree, rows = tm.cookieTree(tree_root)]

Module ZTUtils.Tree, line 139, in getChildren
AttributeError: StructuredTextDocument instance has no attribute
'tpValues'


Does anyone have any hints about how I should proceed now?

Thanks!
Colin
