[Zope-CMF] Adapting ExternalFile for use in CMF

[Kevin Carlson]

I am attempting to adapt the External File product so that it can be used in
CMF.  I am running into an error in what looks to be the area of a guarded
function of some sort.  Here's what I've done so far:

I created a new portal type call CMFExternalFile and set the following:

 MetaType = "External File"
 Product Name = "ExternalFile"
 Factory Method... = "addCMFExternalFile"
 Initial View Name = "manage_addForm"

I also added a python script in the folder /Control_Panel/ExternalFile named
"addCMFExternalFile" with the following lines of code:

   context.manage_addProduct['ExternalFile'].createInObjectManager(id,
context.REQUEST)
   return id

When I try to add a product of type CMFExternalFile from within the CMF I
get the following exception:

   Error Type: AttributeError
   Error Value: createInObjectManager

and the following stack trace:

It appears that the 'createInObjectManager' method doesn't exist -- Any
ideas on where I'm going wrong or on how to accomplish this a different way?

Thanks,
