[Zope] Error Value: can't pickle function objects

[Mohamed Lrhazi]

When I replace :

self.domain = self.ddb.getDomain(REQUEST['YSURLARGS'][1])
self.domainTitle=self.domain.getHTMLDomainName()

with this:

domain = self.ddb.getDomain(REQUEST['YSURLARGS'][1])
self.domainTitle=domain.getHTMLDomainName()

It works.

"domain" above is an instance of a class called Domain, I defined it in a 
module that lives in /usr/local/zope/lib/python/YSDomain and that does not 
implement nor extend any Zope classes or interfaces...

Why does instantiating such an object inside my zope application cause 
"can't pickle function objects" error?


Thanks a lot.
