<p>There are <a href="http://java-source.net/open-source/web-frameworks" rel="noreferrer">zillions</a> of Java web application frameworks.</p>

<p>95% were designed before the modern era of AJAX/DHTML-based development, and that means these new methods are grafted on rather than designed in.</p>

<p>Has any framework been built from the ground up with e.g. <a href="http://extjs.com/products/gxt/" rel="noreferrer">GWT + Extjs</a> in mind?</p>

<p>If not, which framework has adapted best to the world of forms with dynamic numbers of fields and pages that morph client-side?</p>
