[Zope] Product Acquisition problem

hi i posted this question on the zope-dev list, but i forgot to set a subject, so i try it here =) i'm trying to get used to product development, here my problem: a call a method with this path: /poll/question/answer/testMethod in my "poll" class i defined a testMethod which returns "self.getId()" but it shows me always my "poll" ID not the expected "answer" id.... i would like to access the id's like context.getId() does when working in the ZMI (i am new to products) tnx HakTom
