Unfortunately the freshly minted JSF 2.0 spec still doesn’t support a generic Collection interface. Currently only a List is supported and while this does work for many situations, it does cause many issues when you are working with a full JavaEE stack since it may be necessary to use Set or SortedSet when working with JPA.
It hasn’t been used in the past, but it’s time for the users to start voting on java.net. So go there, register and throw some of your votes towards this painful issue.
