[rules-users] human tasks example with 5.0

Can anyone point me to some solid examples for mixing processes with human interaction? I've been trawling through the codebase and it looks like drools is geared to support all kinds of different process mappings (jpdl, ruleflow, bpel, etc.) on the core engine. Looks very cool and potentially powerful, but I'm trying to get my head around how to use it with non-dev users. It seems the design philosophy is to model the domain as Java objects then define rules and flows that use these objects. Trouble is I can't see the interface points to create a UI (rich client or whatever) to have a human user take required actions for various processes. This could be as simple as 'get task and data blob', do something to it, and post it back (correlating the process ID). For point of reference, I was quite familiar with how Weblogic Integration managed processes and human tasks, and also have checked into Singleshot (nice idea, but looks incomplete). At the moment using something like Bonita appears to be the best bet, but with some docs/examples/configuration drools could fit the bill. Then of course I'm hoping there's the infrastructure in place to activate/passivate the processes (memory to disk) on requests/ responses from the human users thanks in advance, Garrett
