#8 — Unable to install flash in COEHS: You are not allowed to access 'images' in this context

The code in question where it fails is this:

   #reindex all multimedia types incase something has changed in the way indexing is done
   pc = site.portal_catalog

   for mediaObj in pc.searchResults(type_name="Multimedia"):
       mediaObj.getObject().reindexObject()

On the cloned Zope I wrapped a try/except around that reindexObject() call:

  #reindex all multimedia types incase something has changed in the way indexing is done
  pc = site.portal_catalog

  for mediaObj in pc.searchResults(type_name="Multimedia"):
      logger.info("about to reindex '%s'" % mediaObj.id)
      try:
          mediaObj.getObject().reindexObject()
      except:
          logger.warn("caught exception")
          import pdb;pdb.set_trace()
          throwaway = True
          logger.warn("continuing...")

and then ran it in the foreground. Basically, out of thousands of things it reindexes, only one causes the exception, and for some reason its security is set so that even as kimadmin I am unable to look at it, neither in code nor in the ZMI.

It's an images folder that I think contains two images. The two images are visible.

but if you try to view the images folder:

http://www.uwosh.edu/coehs/Grants/economics/staff/images

you're asked to log in and even if I log in with a user that has Manager role, I get

Insufficient Privileges

I used the ZMI Ownership tab at one level above, ie.

http://www.uwosh.edu/coehs/Grants/economics/staff/manage

and took ownership of it from kimadmin to nguyen, figuring it might fix the problem, but then when I try to view that images folder I get this error:

I patched the code in the production server and updated uwosh.flash in svn to match:

https://svn.it.uwosh.edu/trac/changeset/2448

The patch corrects the query that looks for objects that may require reindexing, and traps exceptions that might occur during reindexing.

This allowed the quickinstall to proceed. The offending images folder remains in the site. Deletion via python prompt does not work, but with a patch to PortalFolder.py (line 412) it is possible to copy and paste the images folder so that the new copy is fully functional.
