The fifth 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-4 release. Many of the fixes in this release were improvements to client-side JavaScript, including client-side input validation. The way Tapestry forms client-side element ids is now XHTML conformant (no use of the dollar sign, no leading underscores). The Form component has a new listener parameter, success, that is only invoked when validation is successful. 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.
