Hi all. cesium-gwt not updated two year, not full API functional, used old GWT ant etc.
I create new wrapper based on JsInterop for GWT 2.8.0.
Features can read in github - https://github.com/iSergio/gwt-cs
I hope this will be interested for community, and for those who lead the development and use of a great product CesiumJS =)
p.s. Sorry for my english
