[Zope] Cloning a ZClass-Instance

[Sven Hohage]

Hallo Chris,
my reply is late but the problem is already not solved.
I've build a simple ZClass 'News' with base-classes 'ZObject,
ZObjectManager'.
I haven't changed the permission-settings in the product.
The script working on the objects is this:

--------------------------
<dtml-in "objectValues(['news'])">
<dtml-let x="_.getitem('sequence-item')">
 <dtml- call "manage_clone(x,'test',REQUEST)"> 

</dtml-let>
</dtml-in>
--------------------------

The response of Dieter Maurer was, that it is a permission problem
-->"Either you are not allowed to call the ZClass constructor
  at the destination,

  or you are not allowed to access the object to be cloned
  at the destination."
I'm trying to execute the operation with the role 'manager'


That's the traceback:
----------------------
The object holle does not support this operation 
                              
Traceback (innermost last):
