[Zope-CMF] Folders within Layers? Is it possible?

[Beef a]

Howdy All,

I'm working on CMFing an existing Zope Product and have run into a few 
challenges with 'skinning'.

1. The product has lots (potentially hundreds) of skinnable elements (icons, 
dtml etc) arranged in a nice heirarchy.

2. I'd like to keep the skinnable elements organised in a hierarchy rather 
than flatten it out - which seems to be the standard approach.

3. So I've done this;

a). Created a regular Folder object (called MyProduct) in the SkinsTool 
(portal_skins), and
b). Created sub-folders (File System Directory Views) within MyProduct to 
create the necessary hierarchy.

(this also stops me having to define hundreds of layers)

eg: So you can imagine my portal_skins folder looks something like this;

portal_skins/MyProduct/Part1/icon.gif
portal_skins/MyProduct/Part1/hello.dtml
portal_skins/MyProduct/Part2/icon.gif
portal_skins/MyProduct/Part2/hello.dtml

where Part1 and Part2 are Directory Views (again, there can be hundreds of 
'Parts')

Note: Unique 'Part' names are used because elements are not necessarily 
unique (and can't be guaranteed to be unique).  eg: there may be many unique 
'Parts' but all may have an 'icon.gif'

3. Everything works fine so far accept when I attempt to access DTML.

eg: I can access http://<object>/Part1/icon.gif and 
http://<object>/Part2/icon.gif perfectly... but not 
http://<object>/Part1/hello

Depending on how I attempt to access a DTML object, I get one of two 
possible errors;

ERROR 1: Attempting to access http://<object>/Part1/hello (directly via the 
browser)

Module ZPublisher.Publish, line 150, in publish_module
Module ZPublisher.Publish, line 114, in publish
Module Zope.App.startup, line 199, in zpublisher_exception_hook
Module ZPublisher.Publish, line 98, in publish
Module ZPublisher.mapply, line 88, in mapply
Module ZPublisher.Publish, line 39, in call_object
Module Products.CMFCore.FSDTMLMethod, line 141, in __call__
Module DocumentTemplate.DT_String, line 474, in __call__

ERROR 2: Occurs when attempting to access via a CMF action; eg: 
http://<object>/view where the view action has the URL Part1/hello

Traceback (innermost last):
  Module ZPublisher.Publish, line 98, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object
  Module Products.CMFCore.PortalContent, line 125, in view
  Module Products.CMFCore.PortalContent, line 112, in __call__
  Module Products.CMFCore.utils, line 163, in _getViewFor
   - __traceback_info__: ('Tutorial', 'Part1/hello')
  Module OFS.Traversable, line 172, in restrictedTraverse
  Module OFS.Traversable, line 154, in unrestrictedTraverse
   - __traceback_info__: ([], 'hello')
TypeError: unsubscriptable object

ASIDE: Customisation works perfectly for non-DTML (the icons) when I place 
new icons in the custom folder with an appropriate Part folder ;)

So does anyone know what the problem is here?

For the first error it seems the FSDTMLMethod doesn't seem to be aquiring 
the <Object>.

For the second error it seems we can't traverse into File System Folders.

------------
Here's my setup:

Windows XP SP1 (+ every security patch in the world)
Zope 2.6.2
CMF 1.4.2

Any help would be HUGELY appreciated.

Cheers
