Hi Helmut.
Sorry.
I have just noticed your mail.
Well, yes, I have found a solution (although it is more like a workaround).
The problem was that the following python statement
self.erzeuger = AUTHENTICATED_USER
within the constructor of my python-base class SOMEHOW shot the thing and I was unable to get a hand on it anymore (even trying to get these things out manually (but that was another problem ;)
So, I changed the line to:
self.erzeuger = AUTHENTICATED_USER.getUserName()
since all I needed was the name!
That solved it.
I got a similiar thing as I once tried to assign an empty list to an object-member in a xxx_add method by
<dtml-call "REQUEST.set('me', [])">
the result was exactly the same: an object got created and changed its type to the type of the container class after a few (non-deterministic) accesses. Did this with zope 2.1.4/2.1.5/2.1.6 on linux/i386 and win32. Reproducable.
hmmm... bogus. Perhaps a bug in the persistence mechamism??
I do not know. But I do avoid those assignments (although they are not forbidden, are they?)
Interesting to notice: you can use those assignments within methods when you do not store anything.
Sorry for the late answer.
Regards, Ingo.
