Yeah I just upgraded to 2.0.5 and GWT 1.5.2 (it runs a lot faster).
extjs 2.1+ went to GPL after tricking people with LGPL for previous
versions. GWT-ext uses the LGPL version and adds its own stuff on top
(it now has a separate roadmap to extjs, yet it still depends on the old
extjs lib, but I htink it will be less and less over time).
Yep, I moved to gwt-ext 2.0.5 and GWT 1.5.2 as well. Works like charrm...
