The fourth beta release of Tapestry 4.0 is now available. Tapestry is a component based web application framework that provides lots of functionality with minimal Java coding, and creates an environment that supports high levels of reuse. This is another a bug fix release, building on the beta-3 release. Key areas covered are fixes for minor client-side validation problems, fixes for several bytecode enhancement issues (including one that prevent transient page properties from being cleared), and adding of many different localizations of the messages used for form input vield validation. In addition, the default binding concept was removed from Tapestry 4.0. A full listing of bugs fixes is available in the change log. Tapestry is provided as a combined binary/source distribution, and a separate documentation distribution.
