[Zope] __call__ error message - I gave up

[cuiod-tec Jens Gelhaar]

What I like to do is pretty simple, but I don't get it. The following code
snippet is simple and what I want to is straightforward:

<dtml-in "objectItems('DTML Document')">
  <dtml-var sequence-item>
</dtml-in>

All DTML Documents in a Folder should be put together in one document. It
works fine, if there is no reference to another object. But when I put
something like
<dmtl-var imageobject> in one of this DTML Document I get the appended error
message.

Any Idea

Jens
