I recently updated Swlink to version 0.7, new documentation and links
to download are available at http://swlink.sourceforge.net.

Swlink is an open source data binding and event delegation toolkit for
Java. In particular it is a convenient and elegant solution to tie Java
GUI Components to their model and to create delegate methods. Swlink is
based on the underlying concept, that the link between two components
is a first class entity, rather than just a conceptual or accidental
artifact in a gui builder. Swlink is available at
http://swlink.sourceforge.net for download.

New in this release is support for automatic property conversion for
property synchronization, improved samples and improved documentation.
