Hi Sim,
I tried that, but there was no difference...seems like the really useful
stuff is really difficult to do. Coming from the pure OO of Java, I expected
extending objects to be really straightforward. I have spent 10 hours trying
to add one field to an existing object definition.
Are there any logs anywhere in Zope/Plone/CMF? I have hunted for *.log but
cannot find anything except Z2.log which has no errors in it. To get some
idea of what the error may be would probably be useful.
