I am using Ext with PHP (http://www.perfitrak.com and absolutely love it, though have not had a chance to try using it with Seam/GWT yet. From research I have been doing, I would actually recommend using MyGWT instead of GWT-Ext for a GWT/Ext bridge (people seem to think it is better designed). There are also JSF/Ext bridges out there too you might want to investigate. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100961#...
