[xwiki-devs] JS UI framework for rich client interface?

Hello, I would like to modify object/class editor by integrating some richer UI widgets such as tabviews. Apparently, you are trying to get rid of Rico, YUI and trying to do as much as possible with Proto...culous But Protoculous doesn't provide tabviews for example. In this case, what do you advise as JS framework for this? YUI as it is already integrated in XWiki and can be used with velocity? GWT by redeveloping a set of serverside APIs but without the possibility to use velocity? regards Pascal
