There's nothing specifically in the framework, nor anything planned, that
I know of. There is a "ListPropertySelectionModel" in Tassel
(http://www.tapestrycomponents.org/Tassel/app?service=external/ViewComponent&sp=SListPropertySelectionModel)
which does the same thing in almost exactly the same manner (sans the 1.5
requirements).
