[jbpm-dev] Re- IOR gateway

Fri Aug 12 12:14:22 EDT 2011

Can you please point me in the spec (Pages) so I can review it and give you
some feedback and estimations?
I'm pretty sure that we can use a complex converging gateway to cover that
features, but I would like to be sure that we are talking about the same
thing.
Cheers
