Hi,

Last week, there was an exchange going on because I was having trouble copying and pasting in DTML (or Python) from a Folder to a ZClass instance. The thread started with http://www.zope.org/pipermail/zope-dev/1999-August/001248.html

It looks like the problem is that I was creating the ZClass instance and doing the copy/paste operation all at once. If I use one DTML method to create the new objects, and then a second method to do the copy/paste, everything works just fine.

Should there be a problem pasting objects to a new object within the same transaction?

The problem is that manage_pasteObjects needs to be called on an object that is already in the database. A new object doesn't actually get inserted into the database until the transaction commits. The new object needs to have a _p_jar attribute (a database connection) that is not None, which it can then use to reconstitute the source object from the moniker. You cold get around this with sub-transactions, but there is an easier way. Rather than going through monikers, it would easier to use manage_clone which copies and pastes objects directly. I think you want something like: def candp(fobj, tobj, REQUEST): "Copy and paste" for id in fobj.objectIds(): tobj.manage_clone(getattr(fobj,id),id,REQUEST) Note that you need pass REQUEST for security purposes, since manage_clone tries to make sure that you are allowed to add the objects to the destination.
