I'm building a Plone site that is a forest (that is, a bunch of copies) of a "standard tree".  Each node of the standard tree is an instance of a different one of my Archetypes content types.  The different content types are identical except for the fields in their respective schemas.  They all use the same page templates, which are basically the Archetypes base_view.pt and base_edit.cpt and all the macros they use, and the same controller scripts, which basically get data out of and update data back into a relational database.  All the trees in the forest are identical except for identifiers.

They all worked fine - until recently, when one of them started throwing an "insufficient privileges" error when I try to bring up either the "view" or the "edit" version from the end user interface.  Also, when I try to look at the ZMI pages for the problem content objects, I get this AttributeError: "'NoneType' object has no attribute 'setHeader' ".  (Full tracebacks below.)

All instances of this one content type present these same problems.  All instances of all the other content types still work fine.  I have compared the content type definitions of the bad type with the good types, but I can't see any difference that would account for the problem.  I'm out of ideas for where to look.

I'm hoping that someone can check out the tracebacks below and suggest where to look.

Traceback from the ZMI error:

2009-03-24T20:20:03 ERROR Zope.SiteErrorLog http://c.05.luxor.highspeedrails.com/groups/glda/practical-matters/events/event/event-session/manage_main

The "insufficient privileges" error occurs when the controller script that reads from the RDB first tries to access the problem object, 'event-session'.  Here's the traceback:

Ken,

Have you made any changes in your schema, and if so, have you updated
the schema in archetype_tool Update Schema tab?

You may need to post your type definition before anyone can really help you.

Do you by any chance have a field called 'header' or 'time'
in the schema?

Other than that: can you post your schema and class definition?

Larry & Raphael ~

Thanks for your suggestions, and I apologize for not responding sooner - somehow I didn't get e-mail notifications of your replies.  I especially appreciate your willingness to respond to the increasingly quirky and obscure problems that I find myself posting to this list as time goes on (and I get better at solving the easier ones myself) ...

Anyway, I (more or less inadvertently) solved the problem by re-executing a script I have that (re-)executes the PopulatorTool, which is what creates (and recreates) the forest of "standard trees".  I don't know what was wrong with my type definition before, but it works now, so all is well enough.

~ Thanks again
~ Ken
