Hello, This is just a tricky Acquisition question, not a bug, low priority. I have a Folderish (I guess the Digifolk call this a Folderoid, but the source code makes it seem Folderish :) object which is an application wrapper around my own heirarchy of custom folders and widgets. In my app wrapper I define a number of Document objects that are preloaded in my __init__ method. There are three main classes, Trove, TroveFolder, and Trove Item. I have inserted a couple TroveFolder and TroveItem objects in my example tree below to spice it up a bit, only the Documents come loaded by default. Trove Index (Document) FolderIndex (Document) ItemIndex (Document) TroveFolder TroveFolder2 TroveItem TroveItem2 Now for example, TroveItem2 has an index_html method like this: def index_html(self, REQUEST): if REQUEST is not None: return self.ItemIndex(self, REQUEST) This fails. I figure it's because I'm not using ItemIndex in the right context, and Acquisition cannot the method in the top level folder. Also, I'm worried that even if it did the Document would be out of context, thinking it was in the root folder instead of two levels down, right?? So I'm thinking I need some kind of mechanism with __of__ and aq_parent to ascend recursively up tree until it finds an ItemIndex method. Before I try such a beast, am I barking up the wrong tree? Has Acquisition truely escaped me? Michel
