Any web developers here using the Ext UI framework and Java backend?

If so....I gotz some questions and beer!

Do you mean this https://ext-ui.dev.java.net/ or this http://extjs.com/ ?

I heard extjs recently changed their licensing to GPL, which makes it hard to include for commercial projects. 

[ducducgooseme]

Yeah, its extjs.  I have the commercial license.

You using it?  working with JSON/AJAX?

I used it a bit for one GWT project, but nothing heavy.  Using Wicket for most of my web dev work currently.
