The development team released bugfix version 2.0.1 of CPAINT on September 5th.

CPAINT is a open-source (LGPL), multi-language toolkit that helps web developers design and implement AJAX web applications with ease and flexibility.

It is built on the principles of AJAX, utilizing JavaScript and the XMLHttp object on the client-side and the appropriate scripting language on the server-side (PHP / ASP) to complete the full circle of data passing from client to server and back.

CPAINT can be downloaded from sourceforge:
