Hi. I'm in the process of adding a Synchronous Service Invoker Action as per JIRA https://jira.jboss.org/jira/browse/JBESB-2785 Do people have (or know of) any specific requirements? All I have in mind right now is something very simple, which is a "SyncServiceInvoker" action that has 2 config params - service category and service name. It routes to the target service and returns the sync response to the action pipeline for processing by the next action in the pipeline. Anything else?
