Hi James, >From your email It isn't at all clear what you are doing, why you are doing it, let alone what you are doing wrong.
It's very odd that you are trying to add a node as a event handler to the viewer. The OSG has an event traversal that will ensure your node gets events. Please have a look at the examples, and do a search for EventCallback. Also please try and upgrade to 2.8.2, the OSG has improved alot since 2.2. Robert.
