I know that if you've relied on a trigger, then it wouldn't have been enough. I would expect GeneratorLinks to be sufficient, but don't really know enough about the internals of IBO (don't use CachedUpdates myself and don't remember whether the generator is called when you do Append or Post). Since I do think it can be relevant for your question, this reply is sent to both you and the ibobjects list.
