[Zope] XMLRPC and Allow_None

[Laura McCord]

Hi,

 I am getting this error: cannot marshal None unless allow_none is
enabled 
I now it is because I am passing a Null value is there a way to allow
this by just disregarding the function?

This is what my client code looks like:
def dirInfo(userName):
 server = xmlrpclib.Server("http://localhost:8080/RPC2")
 user = server.sample.dirInfo(userName)
 return user

So it passes a userName but if the user name is null it needs to be able
to disregard the request.

Any suggestions?

Thanks,
 Laura
