We're currently running JIRA 5.2.4 and GreenHopper 6.2.1, and I cannot find a way to get epics listed in the product backlog. They do show up in the "epics" panel, but I need a way to include them in the prioritization of the rest of the backlog... Which you should be able to do in a product backlog.
I think it's not a problem with the Scrum board's filter, because I've tried this with a test board whose filter simply is "project = MyProject", and the problem is still present. I suspect that GreenHopper itself is excluding epics. Is this correct?
