If anyone wants to jump on the bleeding edge, I think the next generation of PageFactory is ready for public use. It works pretty much like PageFactory 1, but drops the PageFactory::Base class. Instead, all part management is done directly on your Page subclasses:
class EmployeePage < Page part "first name" part "last name" part "department" end PageFactory 2 also adds management of Page Fields. Everything is on the 2.0 branch, so you'll have to install the extension and manually check out the new branch. It will probably remain as a vendored extension until we see another release of Radiant. As always, comments, questions, and bug reports welcomed and appreciated. j
