OK, I'm so sorry about this, you've been an absolute legend so far,
and I really don't want to push my luck, but each time you solve
something, I find something else that has broken.
This is what my theatre_class_add method looks like (well, an excerpt
anyway).
<dtml-call "REQUEST.set('__name__', REQUEST['id'])">
<dtml-with "theatre_class.createInObjectManager(REQUEST['id'],
REQUEST)">
<dtml-call
"propertysheets.theatre_class_property.manage_editProperties(REQUEST)"
>
<dtml-call "manage_edit('<dtml-var
standard_html_header>\n\n<dtml-var standard_html_footer>', '')">
</dtml-with>
When I try to create a new instance of the zclass in the original
'site' folder (or any of its parent folders except for the root), I
get this error. I do not receive an error and everything works fine
when I create the instance in a new folder on a different 'branch' to
the original.

Like I say, you've been fantastic in helping me. Thanks to you, I now
have a solution whereby I know I can redo all of the class instances I
have created, and be sure that the error won't reappear. However, I'm
sure from what you have said so far, there is a way around this that
doesn't involve me 'writing off' all the instances that I have already
created. My problem is, I'm a little out of my depth here! I don't
understand the different behaviour between different folders.
If you haven't already got tired of this, thanks very much.
