I am wondering about is the nature of the problems with ZClasses that
led to their deprecation. If I move a 2.5.1 installation to 2.11, are
my several existing ZClass-based products going to break in any known
way I should be aware of? Should I consider a last-known-good upgrade
target instead?

It's always been like that, but I'd see it as a bug, so stick it in the

I wonder if the same is for number properties?
OK, now that I've settled my title property conundrum by just calling
the property "name" instead :-\ I go to add a "date" property to my
ZClass and find that it doesn't like that either. Specifically, it
won't let me add a property of type date with no value, giving me an

You will want to pass REQUEST to it so you can use it like the Zope

So, put REQUEST in the parameters list.

this CD class?
This seems to almost work. :-)

Hi everyone,
I'm looking forward to using some PythonScripts as methods of some ZClasses
because it seems like a much cleaner way to do things. I wonder if one of
the PythonScript gurus out there would be willing to show an example of two

I've got a minor problem.
My ZClasses won't update the ClassIcons when I change them.
Has someone implemented an aesthetic-filter?
A great step in AI??

Hi, Aaron
Yes.
If your parent ZClass is constructed properly, you should be able to add
the parent class's management tabs by setting a "view". On the "Views"
tab, look in the Method list for
propertysheets/[ParentClassPropertySheetName]/manage. The properties on
that sheet are accessible just

I have a new question that may (?) be the same old one in a different

of Foo. The Foo object should be able create n instances of the Bar
objects and the Bar object should also be able to create n instances

Is there a reason I can't add a UserFolder (and subsequently

I do not get any errors. But the acl_users folder is not in the
