[jbpm-dev] Re- IOR gateway

Fri Aug 12 12:00:19 EDT 2011

That's what I mention. it can be easy to implement most of the times but
there are also some complex business use case that can complicate the
generic approaches.
Looking at a concrete use case will help a lot to understand what do you
want to achieve.
