[Openflow-dev] Re: "Xor split" feature with Openflow 1.0.2

[Hugo A. C. B. <hco...@pr...>]

Roberto:
   I think the problem is in expression.py module include in Openflow
   I resolved this problem, installing the CMF 1.3 Core products, you can
download from http://cmf.zope.org/download/CMF-1.3

I hope this helps.
