Open Source Document Management System | OpenKM

I try to create workflow for OpenKM 4.0 in Eclipsehttp://eclipse.org/ + jBPM visual editor http://sourceforge.net/projects/jbpm/fi ... 0Designer/, but not successful.
I don't find any documentation or discussion about this question. Is it exist?

Can anybody show me example of approval workflow?

We're finishing OpenKM version 4.1, hope in few weeks it'll be released with better workflow support. I recomend to be waiting during this time and upgrade after to this version - you'll don't need to migrate - only replace war file. We'll put there some minimal examble about workflow.

After this workflow improvement, we will focuse to improve the user documentation. Specially the related to workflow engine.
