Hi, Having had no luck in copying and pasting my objects in DTML, I decided to try an External Method. I wrote a function that takes two arguments: from object and to object. It is supposed to copy all of the objects in the from object (a Folder in this case) into the to object (a ZClass instance that inherits from CatalogAware and ObjectManager). Here is the code: def candp(fobj, tobj): "Copy and paste" ids = fobj.objectIds() if not ids: return cdata = fobj.manage_copyObjects(ids) tobj.manage_pasteObjects(cdata) I get an error that the object that is referred to is not found. Here is the last part of the traceback I get: File C:\Program Files\Byproducts\lib\python\DocumentTemplate\DT_Util.py, line 315, in eval (Object: candp(fobj, this())) File <string>, line 0, in ? File C:\Program Files\Byproducts\lib\python\Products\ExternalMethod\ExternalMethod.py, line 246, in __call__ (Object: candp) (Info: ((<Folder instance at 00B4F2D0>, <KMArticle instance at 01650710>), {}, None)) File C:\Program Files\Byproducts\Extensions\art.py, line 28, in candp (Object: ElementWithAttributes) File C:\Program Files\Byproducts\lib\python\OFS\CopySupport.py, line 198, in manage_pasteObjects (Object: CatalogAware) Copy Error: (see above) As you can see, the DTML is calling the candp External Method with "fobj", with is a Folder and this() which is a KMArticle instance. Any hints? Thanks, Kevin
