What is the best Struts2 compliant LGPL Javascript UI components library out there?

Question

Hi community.

We currently have an application built with Struts 1.2. We are currently migrating it to Struts2 and are looking for a nice LGPL library of UI web components that will still exists within the next couple of years :

• The cream of the cream would have been ExtJS, but the GPL license (and its subtle move from LGPL to GPL) is a No-Go.

• We've then taken at the LGPL fork (GWT-Ext), but it seems that its future is not uncertain as part of the community want to have it evolve with ExtJS (and not stick with 2.0.2...) hence becoming GPL also.

• We've taken a look at Dojo, but we are not sure that it is mature enough.

• We would have loved to use jQueryUI, but there is a big lack of UI components compared to other frameworks.

• Qooxdoo looks amazing, but has no community.

• We've also taken a look at YUI, and it seems promising... But again, there are doubts.

What is your advice on the question?

We are starting a new Struts2 project with jQuery UI and jQuery tools (http://flowplayer.org/tools/index.html). It's got enough stuff for us, but may not provide everything you are looking for.
