[Zope] Openflow product is broken on ZMI

Fri Dec 3 05:02:14 EST 2010

Hi,

I just got OpenFlow1.1.0 downloaded. But didn't know the steps to
install. 

But as I extracted Openflow source tar ball in Zope's
lib/python/Products directory, it created .pyc files for instance.py,
activity.py, openflow.py, process.py, transition.py & workitem.py. & so
because of that I thought that openflow is installed. But after that I
was not able to see that in the Products dir of Zope Management
Interface screen. So after that I implemented the solution that u gave
me in your last mail i.e. to change a line (from
Products.PageTemplates.Expressions import getEngine,
_SecureModuleImporter) in expression.py file. After doing this &
restarting zope now I am able to see the openflow on ZMI.  Thanks a Lot
for Ur invaluable help. 

After all this, I imported my project's code from live server to the
development server (Please note that now I am in the process of setting
up development env set up). But after importing the entire project code
from live to dev server, on ZMI for OpenFlow it is giving error as
'Openflow Product is broken', while on live server it works perfectly.
Only after importing code on dev server ZMI it is showing this error.Pls
note that I am importing my project code in binary form (i.e. in .zexp
format).

On LINUX dev server, I started zope as (./zopectl fg) while doing all
the above stuff. It showed the below error -

Does that mean that OpenFlow is not installed properly? If yes what
steps should I follow to install it?  

Am I missing something?

Thanks a lot In Advance!!!

Thanks & Regards,
