Disinjection happens clears an injected values immediately after the method finishes executing. Note that there was a bug with bijection in Seam 2.1.0 that has since been fixed in Seam 2.1.1, so as I have stated before, I would stick with Seam 2.0.3.CR1 for testing the examples until Seam 2.1.1 is GA (and perhaps even after that).

If considering using Seam 2.1.0.SP1 right now, is it better to wait for Seam 2.1.1.GA?
What are the potential consequences of using 2.1.0.SP1 as far as bijection problems are concerned?
