@All:
Thank you very much for your explanations. That's exactly what made me desperate: Trying to use something without knowing exactly what goes on behind the scenes. Now I know more (a java.util.List gets wrapped into a DataModelList, and how to inject it to another bean), and some of my questions have been completely answered. Thanks for your patience ;).

@Gavin:
No problem. We all know you and the other team members spend a lot of time for other things and you can't be everywhere. I just wanted to point out that Seam's documentation isn't as good as Seam itself. And so many people can't tap the full potential of this framework - that's a real pity.
But it's good that we are explicitly encouraged now to contribute to the Wiki. As I already said I write a diploma thesis, and everything useful about Seam will find it's way into the Wiki. CRUDs are the stuff I currently tinker with (that's why I used that ping pong example last week - passing data from one page to another is on important part of this).
So don't be offended, you're doing a great job ;).
