[Zope] Z Class problem

I'm trying to make a list of available properties in a Z Class like: list = [] for x in context.Control_Panel.Products.MyProduct.MyZClassItem.propertysheets.common. MySheet1.propertyIds(): list.append(x) list.sort() return list This works fine _IF_ the ZClass are located in the root of the product. However I'd like to put this class inside another ZClass. But then I get into problems when trying to find the "path" to the propertysheet. Like (NOT working): context.Control_Panel.Products.MyProduct.MyZClassContainer.MyZClassItem.prop ertysheets.common.MySheet1.propertyIds(): I've tryed with everything in the path, methods, common, methods['MyZClassItem'] etc. - I can't figure it out... HELP ! Regards
