[Zope] PLEASE HELP ME!!!!

[Kevin Dangoor]

Hi,

    An external method is standard (unrestricted) python. What you're
describing sounds like you're trying to get the length of some object that
has no __len__ method defined (and therefore, no concept of length).

    Generally, the first parameter in an external method is self, and you
can get to things in the ZODB via self (self.MyZODBObj, etc.). Python
builtins like len() should just work, and you can freely import other
modules for use.

    You may want to double check that you're not calling len() on something
that has no len...

Kevin
