Re: [Openflow-dev] Getting started with OpenFlow

[Daniele <d.t...@ic...>]

Hello Johan,

OpenFlow and CMF OpwnFlow are two different packages. Please refer to 
www.openflow.it for OpenFlow and www.reflab.it for CMFOpenFlow.

Since I don't feel confident with CMFOpenFlow (I don't know enough about it 
and there are other people taking care of it) I'll be talking about OpenFlow. 
Latest release version of OpenFlow is 1.0.6 so it seems you have the right 
one.

You get the mentioned error because your ZCatalog doesen't have the 
CatalogPathAwareness library. If you switch to Zope 2.6.0 you'll get it by 
default. Or you can try downloading just the latest ZCatalog product.

CMF is not needed for OpenFlow. It should not hurt you either having it or 
not having it installed.

I know documentation about OpenFlow is scarce. And often outdated. I hope 
somebody in the community could help with their experience in using OpenFlow. 
Otherwis you'll have to wait 'till we get it written down. Sorry.

Cheers,
	Daniele =)
