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,
