If not, create it. It is easy, if you are a bit sloppy. * Access to "/": "PARENTS[-1]" * Existence check: "_.hasattr(object,what)" NOTE, that this is the sloppy part. - "_.hasattr" will return true, if "object" has attribute "what" (that is what we want) *OR* when it has acquired such an attribute (we do *NOT* want that here). What we would need is a DTML accessible version of "aq_base". This is trivially handled by an external method. - it returns true, when there is such an attribute. This may not be a folder. You can check "meta_type" to see, it is indeed a folder. * creation: "manage_addFolder" look in the ZDP's (http:zdp.zope.org) object reference for the function's signature. I think, this info is available in the Zope 2.2 help system, too.
