How to trigger user events inside Action Engine (or FGV) between multiple VIs?

[njsss]

I tried to use the AE to trigger user events in two VIs, but not successful. Only one of them can trigger the other depending on which starts first. What's the best way to to make a two-way communication (trigger)? I used to use queue, but since the real application each already has a queue (producer/consumer), and the consumer may have things running blocking the queue listening, which means I'll have to make more queues, that just sort of messy.
