[Zope-CMF] Constructing portal folder based ZClass programmatically

[Antwan Reijnen]

Hi Dieter,

Great! I examined the sourcecode, and now understand quite a bit more. I added id to the REQUEST, and everything works fine now!

The reason I did'nt understand this behaviour was because I used the script for quite a while already, successfully from within the portal content-add interfaces. Via invokeFactory, however, there is no id in the REQUEST however.

Ok, clear now. I added a relevant piece of comment to the ZClass based FAQ Content Type how-to on the CMF dogbowl:

Thanks a lot Dieter, you helped me again!

Greetings, Antwan.
