AFAIK (but I'm no expert), a ZClass inherits its parents' propertysheets and you can access them in the normal way. The problem is that the all the propertysheets have to have different names. Example: If your parent class and the child class both have a property sheet called "Basic", but the child class is hoping to inherit someproperty from the parent class: ParentClass.Propertysheets.Basic.someproperty is ok, but ChildClass.Propertysheets.Basic.someproperty won't work, because "someproperty" is not in ChildClass's "Basic" propertysheet. If your parent class and child class do not share propertysheets with the same name, you *can* access parent properties: ChildClass.Propertysheets.ChildSheet.anotherproperty ChildClass.Propertysheets.Basic.someproperty will both work. If I'm correct, this is all wrong and a bad thing, surely? However that was the worst-explained thing I've ever been responsible for and it's probably wrong. That particular configuration of punctuation in the subject header just struck a chord with me... seb.

I guess I can just use dtml methods that return lists and stuff, but is that as cool?

I want to inherit the properties of one zclass in another zclass, but it seems to cause some namespace clashing... shouldn't this be possible? Working with the instance of the class is fine, but inter-zclass inheritance (acquisition?) would be nice...
Cool feature?
Am I missing something? Thanks,
Alex.
