1. Re: Lazy loading not working
Hi! I have tried to reproduce this issue, however so far it has worked as expected. Could you tell me more about your setup? Ideally the contents of RoutingRule, the properties set in persistence.xml and your db manufacturer/version. If it's not possible to provide the contents of RoutingRule.class, could you try to create a simple reproducer app which you are able to share?
