I have to define multiple subscribers to a topic for push registration. It appears that one can register only one subscriber for each push-registration XML file per the class org.hornetq.rest.queue.push.FilePushStore in its constructor. Is there a plan to allow having multiple push-registrations in a single file? Probably the design is to support the unique id that gets passed for dynamic registration in the add(PushRegistration) API. May be you can support both the use cases?
