[Zope] Class variables in ZClasses

[Darran Edmundson]

Jim, pardon my denseness but I'm still struggling with this.
It seems like your response contains conflicting ideas.

>   app._p_jar.close()

I understand the sentence above and the code snippet to
mean the same.  Namely, that *if* MyProduct.MyZClass had
a properties tag, I could simply use this to add a new 
property which all instances of MyZClass would acquire.
ZClasses don't have property forms and so I use the python
code to add the desired attribute.  However, ...

If I add a ClassVariables propertysheet to MyZClass, won't this
get instantiated every time I create a new MyZClass instance?

It seems to me that "class variables" cannot be added to a ZClass
via the web interface, not just for dictionaries (since this isn't
a recognized Zope property type), but for all property types.

Cheers,
Darran.
