Re: [rules-users] Drools Flow 5.1.0.M1 - Human Task - How to get the WorkItem change state after restart of MinaTaskServer

Kris, Should I look into the latest snapshot regarding this? Is something already in place or will it be in some future releases?

We are currently working on making a more stable communication foundation (where different communication technologies could be used) to solve this issue.
