It depends on your dependencies. GWT 2.2 had a breaking change for some third-party libraries (using GWT generators, by turning some abstract classes into interfaces), so make sure you also update your third-party libraries. Otherwise, things should work without too much breakage AFAICT, and should *also* look the same (again, depending on the additional libraries the project uses). See http://www.gwtproject.org/release-notes.html (and yes, the breaking change in 2.2 is not documented there ¯\_(ツ)_/¯ ) -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
