Firstly, I'm trying to return a lazy list to a dtml-in, but it seems that the __getitems__ are all called up front.... This is the class and the print statement shows up in debugging before any debugging output from within the dtml-in: class LazyList: def __init__(self, root, selections): self._root = root self._selections = selections def __getitem__(self, index): s = self._selections[index] print s.getPath() ##### this is executed for all items before anythingwithin the dtml-in o = self._root.restrictedTraverse(s.getPath()) o.setSelection(s) return o def __len__(self): return len(self._selections) Does this mean that dmtl-in touches all of the objects first for some reason? Or am I missing something? Second hard ?..... Is there any way to wrap a Folder subclassed instance within another class so that I can override some methods on an instance by instance basis? I tried doing a .__class__ replacement, but for whatever reason, Zope machinery seems to keep it from taking effect. Any ideas? I've tried about 5 different approaches to no avail :( Sincerely, Tim McLaughlin -- Tim McLaughlin Iteration ZERO, Inc. - www.iterationzero.com 703.481.3983
