[Zope-dev] Getting Unauthorized from __bobo_traverse__.

[Erik Enge]

Hi!

I've have this custom __bobo_traverse__ hook:

    def __bobo_traverse__(self, REQUEST, name):
        """Intercept the traversal"""
        if name:
            if hasattr(self, name):
                return getattr(self, name)

When I call the object like this:

  /objecta

ie. using __call__ (I guess); everything is ok.  It renders the
index_html (which is a DTMLFile) as expected.  However, when I do
this:

  /objecta/index_html

it raises an Unauthorized on me.  I can't understand why.  I thought
it might have something to do with docstrings, so I tried this:

  def index_html(self):
      """we have a doc string"""
      return DTMLFile('index_html', globals())

And that worked (it didn't render the DTML, but I know how to fix
that).  Making it go back to this:

  index_html = DTMLFile('index_html', globals())

raised an Unauthorized on me again.

Here's the full traceback:

I also tried adding:

  __allow_access_to_unprotected_subobjects__ = 1

just for good measure, but that didn't help either.

Any help on this is greatly appretiated.  :-)
