[Zope] KeyError when HTMLFile returned from subobject of main instance

<dtml-var manage_tabs> are taken from the
manage_options portion of your python code and set up the tabs across the top
of the
management window.

The following is taken from DTMLDocument.py:
        DTMLMethod.manage_options[:2] +
        PropertyManager.manage_options +
and to create your own tabs use Key:Value pairs:
   manage_options = (
      {'label':'Edit', 'action': 'editContentForm'},
      {'label':'View', 'action': 'index_html'},
      {'label':'Properties', 'action': 'viewProperties'},
Where the actions are dtml files in my_product folder.
I am not sure if this answers your question or not (I'm still a Zope/Python
but it would seem that your KeyError would mean that Zope can not access one
of the items in the manage_options code.
