I'd say if you've got a fairly substantial number of classes for a particular function, then you should group them [function].event. I would say certainly use your judgment there. What we want to establish is a general structure. That's just my suggestion. If you have a different viewpoint, please share.

Btw, the main reason this issue comes up in Seam 3 is because the source code is now modularized :) In Seam 2, most of the classes were together and it was more obvious where to stick things.
