Is it possible to define new data types and to add a management tab without using ZClasses or building a new product. Some people like so called "monkey patches" to add new tabs.
Of course, you need write access to the file system to do this.
When not, how do you rate ZClasses in regards of stability and no long term quirks. I am using ZClasses back since Zope 2.1.6. I did not have problems (beside some minor bugs).
The mailing list archives tell you about 1 serious problem: You should not derive from a ZClass in a different product. All other (severe) problems could be resolved.
My question is linked to the problem that I'd like to build a website out of templates which should be for flexibility very small blocks. This means the actual site(i.e. contact_html) is a folder and in this folder are other folders that contains the templates contents. But now I've got the problem to make a clean distinction between folders and folders. This means the folders that are webpages and those that are only templates. Maybe, the CMF related discussion about composite documents is of interest for you...
I do not understand what your folder which is a temple is. But, I would make a Python Product, derived from "Folder" with whatever special it want to have. I cannot easily imagine in what way a folder would be a template, as a folder is essentially a set of objects and a template is something completely different. Dieter
