I'm testing JsInterop with GWT 2.8.0-SNAPSHOT. It works fine with Chrome in
Super Dev Mode but it throws a NPE on Firefox.
Below I pasted the interface and the full stacktrace. Should I have to
create an issue?
Thanks,
This is the interface:
@JsType
public interface Sketch {
void load(String s);
JSONObject save();
@PrototypeOfJsType
static class Prototype implements Sketch {
@Override
public void load(String s) {}
@Override
public JSONObject save() {
return null;
}
}
}
This is the full stacktrace:
