[Zope] RE:Newbie: creating objects programmatically

Thanks to Dmitry and Maik, it works fine. So now I need to set the new ZTP contents to those of a model ZPT. Following Dmitry's advice, I read the ZPT source and figured I could do the following: instance.manage_addProduct['PageTemplates'].manage_addPageTemplate('index_html') instance['index_html'].write(instance.memberIndex.document_src(self)) but no, I get: Error Type: Unauthorized Error Value: You are not allowed to access document_src in this context I am logged in as 'manager'. I have tried: instance['index_html'].write(str(instance.memberIndex)) where memberIndex is a regular file and this works fine, but I want to use a model ZPT. Guidance needed, please!
