Yes, OK. So this relates back to the "who should generate all these IDs" discussion we had earlier. IMHO the app developer should not have to care about the context ID (or generate it). All he would need to do is create a new ActionPublisher and if he chooses not to generate the context ID then it should be generated by libhud. So if the developer passes NULL as a context Id then action_publisher_new() would generate one. Do we actually need action publishers with context id set to NULL anyway?
