JForm Swing data binding and validation framework

Via JavaGeek, I came across JForm which does data binding and validation. The approach looks interesting, but it is different from one I have been thinking of. I’ve been thinking of something that does data binding in a dynamically typed manner, which provides quite a bit of flexibility for the kind of data model you’re working with. JForm does implement some interesting features, though, such as automatic validation and highlighting of the field that is being edited.
