In the dev guide I read this: "Note: as of this writing the aq_inContextOf examples don't work. ... there is a collector entry to change it so that you would get the answer you expect in the above." A search at collector.zope.org for aq_inContextOf returns nothing. I'm not sure if it's working properly or not, because I'm not sure what to expect. Testing with Zope 2.5.1, here's an external method which I expected to return (1, 0) but it returns (1, 1): def tmp_aq_test(self): a = self.paul_stuff.aq_inner b = a.blech.aq_inner c = self.portals.aq_inner return (b.aq_inContextOf(a), c.aq_inContextOf(a, 1)) and my folder structure is like: / - portals ( CMF site)/ - paul_stuff (folder) / - blech (folder) / - tmp_aq_test (Ext. Method) I've also tried having the ext. method return c.aq_chain, which suprisingly gives all kinds of stuff that's not on c's containment path. I thought aq_inner was supposed to only give the containers???
