he's talking about the flexible processes, where rules can control the execution of processes. It's a feature we have, that not many people are aware of - it's not ready for prime time use, still incubator. Krisv will respond in a bit, with some pointers.

What you seem to be looking for is a "Conditional Start Event" where you can define the condition using Drools syntax. What you should do when you want to introduce a "wait point" is to do the merge of you current flow with one of this Conditional Start Event using an Converging Parallel Gateway. The gateway will not continue its execution until all of its branches get executed.
That is a 100& BPMN2 solution (you could also use complex gateways, but I'm not sure in which degree are they supported in jBPM5).
Another solution, more user friendly and even easier to implement and maintain is to use asynchronous work items that will be completed by rules when certain condition is met. The good thing about this solution is that is easy to create your own task definition to put in the editor palette and that you can create a single work item handler and reuse it for all your 'wait points'.

Salaboy, the issue I have is that I want users to be able to see the process
graphically, so I think that means I need one overall process (I may use a
few sub-processes).  Using rules however as you suggest is there a way to
"pause" a process until a message (/signal) with certain criteria is
inserted?  I thought about using a business rule task, with a rule that
would always be false (until the node should allow processing to pass
through), but I could not get that working.

I also saw a suggestion about adding a "Condition" to the metadata for a
timer node, but that doesn't seem to be working either.

Mark - thanks for the information.  I'm looking at flexible processes now
and will be in touch with Kris.

Thanks again,
