I have a similar question, but I'm working with ZClasses. If I subclass Folder, I get a pick list of all possible classes that I can add to my object. If I subclass ObjectManager, I don't automatically get any list of classes that I can add to my object. I presume that I have to do something to generate the list of classes that I want to be able to add, but I don't know what I have to do. Can someone help get me pointed in the right direction. -- Thanks -- Loren

Hi there,
I'm writing a product (in Python, not with ZClasses) which consists of:
form - a folderish object to which you can add.. fields - a number of SimpleItemish objects that can be added to a form
What I have working:
* I can make the form behave like a folder by deriving it from OFS.ObjectManager
* I have a number of fields that can be added anywhere in the Zope tree
What I want to reach is this situation:
* I want the form to behave like an folder, but only fields should be addable.
and
* Fields should not be addable anywhere but in a form.
What set of incantations would accomplish this? Any example source? Or Zope source code I should study? Anything? Any hint in the right direction would be appreciated.
Regards,
Martijn
