I'm not sure what I did wrong, but Zope seems to be reporting something from deep within...

The error message is just

Error Type: Type Error Error Value: first argument must be sequence of strings

the last message in the stack trace is

<zopedir>/lib/python/Zope/__init__.py, line 250, in recordMetaData

If I open up __init__.py for Zope (shiver), the line in question is the second one from the pair below:

if hasattr(object, getPhysicalPath): path = join(object.getPhysicalPath(), '/')

So it looks like somewhere along the line, my object must have overridden getPhysicalPath, but I certainly don't have any method with a name like that, and I'm subclassing SimpleItem.SimpleItem. I would insert

print object, object.getPhysicalPath, object.getPhysicalPath() before the failing line to learn what object (type) causes the problem and how precisely it looks like. I would expect the call to "getPhysicalPath" returns "None", probably a bug... Dieter
