Hello Chris,

No, no mounted database. The culprit was something
bad (?) I was doing.

Blark is a Portal Folder subclass that contains regular
portal Document class instances.  I found that if someone
were to use the normal portal search (say, using the
textfield in the 'top bar') then unpublished articles would
show up.

Clicking on such links cause various bad things to happen.
It's not possible to check published state of a Document
unless you're the owner (why not? I still think that's a
mistake) so that skins/generic/search can't be repaired.

So anyway, I thought I'd be smart and modify the view attribute
of a document to point to something else that could check the review
state (within python code it can be done) prior to displaying the
Document's content. When someone creates a new article for
Blark, a new Document instance is created, then I do:

        ob = self._getOb(str_id, self)
        ob.view = self.document_view

where document_view is defined in Blark.py.

This solves the problem, but Zope complains after you do it
a number (1<n<20) times. Beyond my Zen Level....

Oh well.....

Jeff
