Hello community:
I'm using GWT 2.8-SNAPSHOT and new annotations JsInterop.
I have a very simple class, but gives the error in compilation time.
@JsType(isNative = true, name = "Object", namespace = JsPackage.GLOBAL)
public class JsObject {
public static native List getOwnPropertyNames(Object obj);
}
public class gwt_sample implements EntryPoint {
@Override
public void onModuleLoad() {
JsObject.getOwnPropertyNames(new String());
}
}
