Thanks Ray, I appreciate the detailed response. We do most of our rendering server-side and use very few widgets, so it sounds like we'll be fine. We don't use any panels other than FlowPanel and we use simple widgets like Hyperlink and CheckBox with a few cases of SuggestBox and our own wrapper around a DateBox<http://gwt-traction.googlecode.com/hg/demo/com.tractionsoftware.gwt.demo.utcdatebox.UTCDateBoxDemo/UTCDateBoxDemo.html>. We started using GWT with 1.5 and so have never used UiBinder and all of our CSS is done with SASS on the server-side.
That said, we have over 150k lines of GWT (including whitespace, comments, etc) and are pretty committed to it. We may be a bit unique, but we use GWT mostly as a (much, much) better version of coffeescript and rely heavily on the DOM/event abstractions, deferred binding, code optimization, JSNI, and RPC, and of course the ability to use Java for all of this. Thanks for all of the great work you guys have done over the years. I'm really looking forward to 3.0. -Andy On Friday, October 25, 2013 1:21:22 PM UTC-4, Ray Cromwell wrote: > > > I think what we're really thinking about doing is preserving IE8 for the > existing gwt widget stuff, but any features (APIs) we add going forward are > going to leverage modern browser stuff, and we are not going to design > (poorly performing, hacky) fallback/polyfill workarounds. > > For GWT 3.0, we are looking at making a new, parallel way of writing Web > UIs that is based on the emerging Web Components standard, and we will lean > heavily on modern browser layout engines, e.g. flexible box model.
