[Zope-CMF] CMF custom Portal Product / portal_type

[Mr. Udatny]

When i try to add new....
check an available, custom portal_type
give it an id, submit the whole thing,
then i get always the same error;


Zope has encountered an error while publishing this resource.

Error Type: AttributeError
Error Value: __getslice__



i use;
CMF 1.2
Zope 2.4.3 win

must have to do something with the content creation,
it happens also when i follow the PortalPolls Tutorial. Same effect.
Any ideas? its kind of urgent to get any helpful hints. thanks.

(shall i go back a version - and try again?)
