[Zope] multi-level acquisition (or the "images" folder problem) - still a problem ;)

[wazum-mail (wolfgang)]

Hiya!

this doesn't work for me ...

only the folder "images" is a CascadingFolder ...

I get this error message:

You can also use my CascadingFolder instead of a normal Folder:

http://www.spoke.net/randy/CascadingFolders.tgz

Given Tim's diagram:
> /
> |
> +-/images
> | |
> | +-img1
> |
> +-/index_html
> |
> +-/folder
>   |
>   +-/images
>   | |
>   | +-img2
>   |
>   +-/index_html
>
> ...and edit the tag in /folder/index_html to say
>
> <dtml-var "images.img2">
> <dtml-var "images.img1">

If folder.images is a CascadingFolder, both of these dtml-var statements
will work.
