Sorry the subject is not so discriptive, but here is the issue I am dealing with. I wonder whether this has to do with the way Zope deals with objects or has something to do with Python: I have an Python Product class "Object". With the following bits of code, I get different results from a <dtml-var>, depending on what I use. class Object(PropertyManager, Implicit, Item): def get_path(self): """Return a path to myself""" path=string.join(self.getPhysicalPath()[1:], '/') return path def __getattr(self, attr): """Return a path to myself""" if attr == 'path': path=string.join(self.getPhysicalPath()[1:], '/') return path else: raise AttributeError, attr Now the following two dtml tags yield: <dtml-var "get_path()"> => /path/to/object <dtml-var "path"> => object Hopefully you see what I mean. Why does this happen? Can I put it in the collector as a bug? TIA, Ziniti
