Hi,
my folderish ZClass Product already contains an index_html document. I would like to provide users with a possibility to create a local index_html document in their instance of the product. but if I create a local index_html, I get a key error: "already in use". Is this a general ZClass problem?
No, it is by design. ObjectManagers do not allow you to create an object contained in them that allready uses that id, *or is allready an attribute (like a method) of that ObjectManager*. Your ZClass does not 'contain' a method object. Rather, the method object is a method of your ZClass. The method managment view *looks* like the container managment view, but it is a different beast. methods in the ZClass Methods view will become attributes of your ZClass instances, *not* children in a containment relationshipsub-objects. When you try and create a sub-object of your object it gives you an error because your objects (an instance of your ZClass) allready has an attribute (a method) by that name.
Is there a solution?
Have your ZClass's index_html method defer it's action until run-time: <dtml-if FrontPage> <dtml-var FrontPage> <dtml-else> <dtml-var myObscureDefaultContent> </dtml-if> Make 'myObscureDefaultContent' a method of your ZClass, this is what is your index_html method of the ZClass now. If the user creates a new method in the ObjectManager called 'FrontPage', it will be displayed instead. -Michel
