Hi, I've finally gotten around to doing the PathHandler product I mentioned ages ago and now I've run into problems. Since it's so short, here's the product class: class PathHandler( SimpleItem,Persistent,Acquisition.Implicit ): meta_type = 'Path Handler' def __init__(self, id, method_name, title=''): """initialise a new instance of Path Handler""" self.id = id self.title = title self.method_name= method_name def __bobo_traverse__(self, TraversalRequest, name): list=copy(TraversalRequest['TraversalRequestNameStack']) list.reverse() TraversalRequest['path_to_handle']=[name]+list TraversalRequest['TraversalRequestNameStack']=[] return getattr(self,self.method_name) Okay, the confusing bit first. Let's say x is an instance of PathHandler, with method_name = 'the_method'. the_method is a DTML method as follows: <dtml-var standard_html_header> <h2><dtml-var title_or_id> <dtml-var document_title></h2> <p> <dtml-var path_to_handle> </p> <dtml-var standard_html_footer> If I try the url: http://localhost:7080/x ...I get: Resource not found <!-- PathHandler instance at 011F5500 --> Traceback (innermost last): File E:\Zope\2271B4~1.2\lib\python\ZPublisher\Publish.py, line 222, in publish_module File E:\Zope\2271B4~1.2\lib\python\ZPublisher\Publish.py, line 187, in publish File E:\Zope\2271B4~1.2\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File E:\Zope\2271B4~1.2\lib\python\ZPublisher\Publish.py, line 173, in publish File E:\Zope\2271B4~1.2\lib\python\ZPublisher\HTTPResponse.py, line 308, in setBody File E:\Zope\2271B4~1.2\lib\python\ZPublisher\HTTPResponse.py, line 529, in notFoundError NotFound: (see above) If I try the url: http://localhost:7080/x/1 ...I get what I expect, the output of the_method, with path_to_handle set to ['1'] Now, if I try the following url or anythong longer: http://localhost:7080/x/1/2 ...I get: Zope has encountered a problem publishing your object.
