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.

When I try to copy and paste a zclass from this 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 copy and
paste an instance in a new folder on a different 'branch' to the
original.

"One or more items referred to in the clipboard data was not found.
The item may have been moved or deleted after you copied it."


When I try to rename a class that is in the original 'site' folder (or

not receive an error and everything works fine when I rename an

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.
