What's the best practice for implementing Scatter-Gather (http://www.eaipatterns.com/BroadcastAggregate.html) in JBoss ESB SOA-P?
I don't think Aggregator is intended for possibly long-running services like this. Would one use jBPM or maybe a scheduled custom service/action that looks for necessary response messages to be present?
Right... I think you'd need to use a jBPM join for aggregation on long running processes. Not sure how that works if the splitting/forking is outside the process.
