 gets an argument (probably "getProperty(id)") that is
not a sequence, it even does not support the "len" operation.

I assume that you somehow managed to assign a non-list value
(maybe None or a number) to a list valued property.

[Zope] Stranger than Property

2000-09-11 Thread Sven Hohage 

Hallo,
I've got a very strange error.
I'm working with external methods and folder proprties. The methods are
iterating over properties
and adding or deleting items.
Until friday everything was fine.Now I got this error when I try to view
the properties.
I'm not understanding why there is a mistake only by viewing the
properties.
