Here’s a brain dump of my current thoughts on Web Frameworks:
Wicket. More complicated than Click and generates less HTML for you. However, it would work well with Web designers - templates are valid XHTML. I like it but the documentation leaves something to be desired.
On the radar is JSF, GWT, Tibco GI, Yahoo UI, Dojo:
GWT. Looks great for single-page web applications like Gmail.
will update again soon…
