[Zope-CMF] Re: Invoke factory?

[Carl Rendell]

I'll put this on the list for consumption...

I've been working with an update package creates copies of all 
items created with ZClass based products, and creates a new version 
from a folder based equivalent. This is all done via a python 
script implemented as an external method. It's being performed on a 
rather old platforms - Zope 2.4.1/CMF 1.1 , Zope 2.4.1/CMF 1.2

In my testing I found some strange behavior.. When attempting to 
create a copy of the object using invokeFactory(), I would receive 
the traceback listed below.

After performing more testing, I found that invokeFactory() DOES 
function in this environment, but ONLY when the portal_type is 
configured to use a file based product. If the portal_type is 
configured to use a ZClass based product, the traceback rears its 
ugly head.

At this point I understand the circumstances for the behavior, and 
have a work-around so I'm not going into the problem any deeper. To 
sum up my experience...

someFolderObject.invokeFactory('myobjectid','portal_type')

Is the preferred method for adding content, but can be a challenge 
to use if your products are ZClass based.
