HAI list,
I am developing a zope product composed of a bunch of python classes, some which are instanciated in the ZODB, like plone's tools, and some that are just helper classes, they do not need to be instanciated in the ZODB.
UserManager is a class that is in the ZODB. UserManager retrieves users from MySQL, and create User objects. User is a classic python class (that is not instanciated in the ZODB).
For every user, i wish to display its profile on the site using a Page Template. So I tried something like this :
from Products.PageTemplates.PageTemplateFile import PageTemplateFile
from AccessControl                           import ClassSecurityInfo
from Utilisateur                             import Utilisateur
import Globals
class User() :
   security = ClassSecurityInfo()
   security.declareObjectPublic()
   security.setDefaultAccess("allow")
userProfile = PageTemplateFile("views/userProfile.pt",globals())
...
Globals.InitializeClass(User)
Then, in UserManager, I have another Page Template that displays a user profile this way :
<html>
<body>
 <h1>User profile </h1>
 <hr/>
 <ins tal:define="myUser request/SESSION/myUser" tal:replace="myUser/userProfile"
</body>
</html>
This code produces the following error :
Module ZPublisher.Publish, line 101, in publish
Module ZPublisher.mapply, line 88, in mapply
Module ZPublisher.Publish, line 39, in call_object
...
Module Shared.DC.Scripts.Bindings, line 1, in ?
Module Shared.DC.Scripts.Bindings, line 286, in _getTraverseSubpath
AttributeError: 'str' object has no attribute 'other'
Any ideas ?
What version of zope are you running? Can you edit
Shared.DC.Scripts.Bindings, at line 286, and see what is the code
saying there. In Zope 2.9.6 the only occurence of "other" inside
Bindings.py is:

    def _getTraverseSubpath(self):
        # Utility for bindcode.
        if hasattr(self, 'REQUEST'):
            return self.REQUEST.other.get('traverse_subpath', [])
        else:
            return []

So, I assume for some very strange reason other is applied to
something which is a string. Have you tried to add an

import pdb; pdb.set_trace()

just before the return, and inspect what is going on there? Of course,
you've to run your zope instance in foreground...

I suggest you to check python pages on pdb, and on how to debug things
with zope debug.

Marco
