[Zope-CMF] Constructing portal folder based ZClass programmatically

[Antwan Reijnen]

Hi all,

I send this message again, because I forgot to include the error traceback (thanks Dieter!).

I use Zope 2.3.3, and CMF 1.2. 

I created a ZClass based on Portal Folder. I used two different methods in a Python Script to add an instance to a portal folder in a portal, and both failed with the same error. 

The two methods do however create other portal-content-based ZClasses instances correctly! 

The first method goes like this and as said, works correctly for my normal portalcontent based ZClasses:

myPortalFolderInWhichTheContentGoes.invokeFactory
(type_name='PortalFolderBasedZClassContentType', id='my_folder_based_content')

It complains:

Error Type: TypeError
Error Value: argument id was ommitted

The second method, which also works correctly for normal portalcontent based ZClasses, goes like this:

context.portal_types.constructContent(type_name='PortalFolderBasedZClassContentType', container=myPortalFolderInWhichTheContentGoes, id='my_folder_based_content')

It also complains:

Error Type: TypeError
Error Value: argument id was ommitted

It seems that the id-parameter is swallowed somewhere in the proces. Anyone who experienced the same problems?

I hereby attatch the traceback for more clues.
  
Any clues will be appreciated.

TIA, Antwan.
