I just posted this regarding Manager component pattern (@Unwrap) under design patterns. Enjoy.
I'd like to hear about real-world use cases of using @Unwrap, I know there's several instances in the Seam API. Specifically, why you would replace @Factory with @Unwrap and when?
I've recently run into some stale data problems with @Factory and back button, etc. that I had to manually set to null so the @Factory methods would re-fire and refresh the data/ListDataModels for the dataTables.
Does anybody use @Unwrap with @DataModel??
